Goldman Sachs Data Engineer at a Glance
Interview Rounds
6 rounds
Difficulty
When a batch job feeding Goldman's SecDB risk system fails at 6:47 AM, someone on the data engineering team gets a call from a managing director, not a Jira notification. From what candidates tell us, that urgency is the single biggest culture shock for people coming from pure tech companies. GS also happens to maintain Legend, an open-source data management platform, which signals an engineering ambition most people don't associate with a bank.

Practice with real questions.
You're building and maintaining the pipelines that feed trading risk models, portfolio analytics, client reporting, and regulatory compliance inside divisions like Asset & Wealth Management. The day-to-day means owning Airflow DAGs end to end, shipping ingestion pipelines for new data sources into the Legend platform, and working directly with quant teams who depend on your output before markets open.
A Typical Week
A Week in the Life of a Goldman Sachs Data Engineer
Typical L5 workweek · Goldman Sachs
Weekly time split
Culture notes
- Goldman expects consistent in-office presence five days a week at 200 West Street, and the pace is intense — data pipelines feed risk and PnL systems that senior leadership monitors daily, so reliability is non-negotiable.
- Hours typically run 8:30 AM to 6:30 PM with occasional late nights around quarter-end reporting or major platform migrations, and the engineering culture has modernized significantly with open-source contributions like Legend but retains Goldman's signature rigor around code quality and documentation.
The infrastructure slice is what catches people off guard. You might picture yourself writing Spark transformations all day, but a meaningful chunk of each week goes to debugging failed DAGs, fixing partition skew on cluster jobs, and cleaning up deprecated pipelines nobody wants to touch. The writing load is also real: Goldman's documentation culture means you're producing design docs, runbooks, and on-call handoff notes regularly. If you hate prose, that'll be a friction point.
Projects & Impact Areas
Pipeline work for Asset & Wealth Management sits at the center, where you might build the orchestration layer to land a new satellite imagery dataset in S3, validate it with Great Expectations, and load it into Legend for the quant strategies group. Regulatory and compliance flows (SEC reporting, audit trails, risk aggregation) run alongside that work and demand bulletproof lineage. Less glamorous, arguably higher stakes, since a data quality gap in a compliance pipeline has consequences that go well beyond a broken dashboard.
Skills & What's Expected
SQL and Python are expected, but comfort with the JVM ecosystem is the skill most candidates underestimate. Goldman maintains significant Scala and Java tooling internally, and engineers who arrive knowing only Python often face a steeper ramp. The structured skill profile shows medium demand across every dimension, which in practice means pipeline reliability and data quality are where you earn trust, while deep ML theory rarely comes up in the actual work.
Levels & Career Growth
Where people get stuck is the Associate-to-VP transition. Earlier promotions tend to follow a predictable timeline if you're performing, but VP requires visible architecture ownership or cross-team platform leadership, not just solid execution on assigned tickets. Lateral moves into quant engineering, data science, or platform infrastructure are common and genuinely supported, which makes the banking-style hierarchy more flexible than it looks on paper.
Work Culture
Goldman expects consistent five-day in-office presence (at 200 West Street for the NYC team), with hours that from candidate reports run roughly 8:30 AM to 6:30 PM and stretch later around quarter-end reporting. The engineering culture has modernized (Legend, modern tooling, open-source contributions), but GS's signature rigor around code quality and documentation remains. If your pipeline breaks, you own the fix and the postmortem, and that accountability is both the hardest and most growth-accelerating part of the job.
Goldman Sachs Data Engineer Compensation
The provided compensation data for this role is too sparse to make specific claims about bonus percentages, vesting schedules, or benefits. If you're evaluating a GS offer, compare it against the full picture (base, bonus, deferred comp, and benefits) rather than fixating on base salary alone, since Wall Street comp structures differ fundamentally from tech industry packages built around RSU grants.
Without verified level-by-level data, the most Goldman-specific negotiation advice is this: research the division you're joining. Asset & Wealth Management, Global Banking & Markets, and Platform Solutions each have different revenue profiles that influence discretionary bonus pools, so the same title at two different desks can yield meaningfully different total comp over time.
Goldman Sachs Data Engineer Interview Process
6 rounds·~5 weeks end to end
Initial Screen
2 roundsRecruiter Screen
An initial phone call with a recruiter to discuss your background, interest in the role, and confirm basic qualifications. Expect questions about your experience, compensation expectations, and timeline.
Tips for this round
- Prepare a crisp 60–90 second walkthrough of your last data pipeline: sources → ingestion → transform → storage → consumption, including scale (rows/day, latency, SLA).
- Be ready to name specific tools you’ve used (e.g., Spark, the company, ADF, Airflow, Kafka, the company/Redshift/BigQuery, Delta/Iceberg) and what you personally owned.
- Clarify your consulting/client-facing experience: stakeholder management, ambiguous requirements, and how you communicate tradeoffs.
- Ask which the company group you’re interviewing for (industry/Capability Network vs local office) because expectations and rounds can differ.
Hiring Manager Screen
A deeper conversation with the hiring manager focused on your past projects, problem-solving approach, and team fit. You'll walk through your most impactful work and explain how you think about data problems.
Technical Assessment
2 roundsSQL & Data Modeling
A hands-on round where you write SQL queries and discuss data modeling approaches. Expect window functions, CTEs, joins, and questions about how you'd structure tables for analytics.
Tips for this round
- Be fluent with window functions (ROW_NUMBER, LAG/LEAD, SUM OVER PARTITION) and explain why you choose them over self-joins.
- Talk through performance: indexes/cluster keys, partition pruning, predicate pushdown, and avoiding unnecessary shuffles in distributed SQL engines.
- For modeling, structure answers around grain, keys, slowly changing dimensions (Type 1/2), and how facts relate to dimensions.
- Show data quality thinking: constraints, dedupe logic, reconciliation checks, and how you’d detect schema drift.
System Design
You'll be given a high-level problem and asked to design a scalable, fault-tolerant data system from scratch. This round assesses your ability to think about data architecture, storage, processing, and infrastructure choices.
Onsite
2 roundsBehavioral
Assesses collaboration, leadership, conflict resolution, and how you handle ambiguity. Interviewers look for structured answers (STAR format) with concrete examples and measurable outcomes.
Tips for this round
- Use STAR with measurable outcomes (e.g., reduced pipeline cost 30%, improved SLA from 6h to 1h) and be explicit about your role vs the team’s.
- Prepare 2–3 stories about handling ambiguity with stakeholders: clarifying requirements, documenting assumptions, and aligning on acceptance criteria.
- Demonstrate consulting-style communication: summarize, propose options, call out risks, and confirm next steps.
- Have an example of a production incident you owned: root cause, mitigation, and long-term prevention (postmortem actions).
Case Study
This is the company's version of a practical problem-solving exercise, where you'll likely be given a business scenario related to data. You'll need to analyze the problem, propose a data-driven solution, and articulate your reasoning and potential impact.
The timeline from first recruiter call to offer varies, but candidates on forums and in interview-sharing communities frequently describe loops in the range of four to eight weeks. Where the process stalls is often after the final round, when you're waiting on a decision with little communication. That silence can feel like a rejection when it's really just bureaucracy.
The non-obvious thing worth knowing: behavioral performance at Goldman carries weight that surprises candidates coming from pure tech backgrounds. GS interviewers across divisions reportedly probe for composure under operational pressure, think "walk me through a time a critical deliverable broke at the worst possible moment." A polished system design answer paired with vague or rehearsed-sounding behavioral responses is, from what candidates describe, a more common failure mode than struggling with a SQL window function.
Goldman Sachs Data Engineer Interview Questions
Data Pipelines & Engineering
Expect questions that force you to design reliable batch/streaming flows for training and online features (e.g., Kafka/Flink + Airflow/Dagster). You’ll be evaluated on backfills, late data, idempotency, SLAs, lineage, and operational failure modes.
What is the difference between a batch pipeline and a streaming pipeline, and when would you choose each?
Sample Answer
Batch pipelines process data in scheduled chunks (e.g., hourly, daily ETL jobs). Streaming pipelines process data continuously as it arrives (e.g., Kafka + Flink). Choose batch when: latency tolerance is hours or days (daily reports, model retraining), data volumes are large but infrequent, and simplicity matters. Choose streaming when you need real-time or near-real-time results (fraud detection, live dashboards, recommendation updates). Most companies use both: streaming for time-sensitive operations and batch for heavy analytical workloads, model training, and historical backfills.
You ingest Kafka events for booking state changes (created, confirmed, canceled) into a Hive table, then daily compute confirmed_nights per listing for search ranking. How do you make the Spark job idempotent under retries and late-arriving cancels without double counting?
You need a pipeline that produces a near real-time host payout ledger: streaming updates every minute, but also a daily audited snapshot that exactly matches finance when late adjustments arrive up to 30 days. Design the batch plus streaming architecture, including how you handle schema evolution and backfills without breaking downstream tables.
System Design
Most candidates underestimate how much your design must balance latency, consistency, and cost at top tech companies scale. You’ll be evaluated on clear component boundaries, failure modes, and how you’d monitor and evolve the system over time.
Design a dataset registry for LLM training and evaluation that lets you reproduce any run months later, including the exact prompt template, filtering rules, and source snapshots. What metadata and storage layout do you require, and which failure modes does it prevent?
Sample Answer
Use an immutable, content-addressed dataset registry that writes every dataset as a manifest of exact source pointers, transforms, and hashes, plus a separate human-readable release record. Store raw sources append-only, store derived datasets as partitioned files keyed by dataset_id and version, and capture code commit SHA, config, and schema in the manifest so reruns cannot drift. This prevents silent data changes, schema drift, and accidental reuse of a similarly named dataset, which is where most people fail.
A company wants a unified fact table for Marketplace Orders (bookings, cancellations, refunds, chargebacks) that supports finance reporting and ML features, while source systems emit out-of-order updates and occasional duplicates. Design the data model and pipeline, including how you handle upserts, immutable history, backfills, and data quality gates at petabyte scale.
SQL & Data Manipulation
Your SQL will get stress-tested on joins, window functions, deduping, and incremental logic that mirrors real ETL/ELT work. Common pitfalls include incorrect grain, accidental fan-outs, and filtering at the wrong stage.
Airflow runs a daily ETL that builds fact_host_daily(host_id, ds, active_listings, booked_nights). Source tables are listings(listing_id, host_id, created_at, deactivated_at) and bookings(booking_id, listing_id, check_in, check_out, status, created_at, updated_at). Write an incremental SQL for ds = :run_date that counts active_listings at end of day and booked_nights for stays overlapping ds, handling late-arriving booking updates by using updated_at.
Sample Answer
Walk through the logic step by step as if thinking out loud. You start by defining the day window, ds start and ds end. Next, active_listings is a snapshot metric, so you count listings where created_at is before ds end, and deactivated_at is null or after ds end. Then booked_nights is an overlap metric, so you compute the intersection of [check_in, check_out) with [ds, ds+1), but only for non-canceled bookings. Finally, for incrementality you only scan bookings that could affect ds, either the stay overlaps ds or the record was updated recently, and you upsert the single ds partition for each host.

Data Warehouse
A the company client wants one the company account shared by 15 business units, each with its own analysts, plus a central the company X delivery team that runs dbt and Airflow. Design the warehouse layer and access model (schemas, roles, row level security, data products) so units cannot see each other’s data but can consume shared conformed dimensions.
Sample Answer
Most candidates default to separate databases per business unit, but that fails here because conformed dimensions and shared transformation code become duplicated and drift fast. You want a shared curated layer for conformed entities (customer, product, calendar) owned by a platform team, plus per unit marts or data products with strict role based access control. Use the company roles with least privilege, database roles, and row access policies (and masking policies) keyed on tenant identifiers where physical separation is not feasible. Put ownership, SLAs, and contract tests on the shared layer so every unit trusts the same definitions.
A Redshift cluster powers an operations dashboard where 150 concurrent users run the same 3 queries, one query scans fact_clickstream (10 TB) joined to dim_sku and dim_marketplace and groups by day and marketplace, but it spikes to 40 minutes at peak. What concrete Redshift table design changes (DISTKEY, SORTKEY, compression, materialized views) and workload controls would you apply, and how do you validate each change with evidence?
Data Modeling
Rather than raw SQL skill, you’re judged on how you structure facts, dimensions, and metrics so downstream analytics stays stable. Watch for prompts around SCD types, grain definition, and metric consistency across Sales/Analytics consumers.
A company has a daily snapshot table listing_snapshot(listing_id, ds, price, is_available, host_id, city_id) and an events table booking_event(booking_id, listing_id, created_at, check_in, check_out). Write SQL to compute booked nights and average snapshot price at booking time by city and ds, where snapshot ds is the booking created_at date.
Sample Answer
Start with what the interviewer is really testing: "This question is checking whether you can align event time to snapshot time without creating fanout joins or time leakage." You join booking_event to listing_snapshot on listing_id plus the derived snapshot date, then aggregate nights as $\text{datediff}(\text{check\_out}, \text{check\_in})$. You also group by snapshot ds and city_id, and you keep the join predicates tight so each booking hits at most one snapshot row.
1SELECT
2 ls.ds,
3 ls.city_id,
4 SUM(DATE_DIFF('day', be.check_in, be.check_out)) AS booked_nights,
5 AVG(ls.price) AS avg_snapshot_price_at_booking

10GROUP BY 1, 2;You are designing a star schema for host earnings and need to support two use cases: monthly payouts reporting and real-time fraud monitoring on payout anomalies. How do you model payout facts and host and listing dimensions, including slowly changing attributes like host country and payout method, so both use cases stay correct?
Coding & Algorithms
Your ability to reason about constraints and produce correct, readable Python under time pressure is a major differentiator. You’ll need solid data-structure choices, edge-case handling, and complexity awareness rather than exotic CS theory.
Given a stream of (asin, customer_id, ts) clicks for an detail page, compute the top K ASINs by unique customer count within the last 24 hours for a given query time ts_now. Input can be unsorted, and you must handle duplicates and out-of-window events correctly.
Sample Answer
Get this wrong in production and your top ASIN dashboard flaps, because late events and duplicates inflate counts and reorder the top K every refresh. The right call is to filter by the $24$ hour window relative to ts_now, dedupe by (asin, customer_id), then use a heap or partial sort to extract K efficiently.

Data Engineering
You need to join a 5 TB Delta table of per-frame telemetry with a 50 GB Delta table of trip metadata on trip_id to produce a canonical fact table in the company. Would you rely on broadcast join or shuffle join, and what explicit configs or hints would you set to make it stable and cost efficient?
Sample Answer
You could force a broadcast join of the 50 GB table or run a standard shuffle join on trip_id. Broadcast wins only if the metadata table can reliably fit in executor memory across the cluster, otherwise you get OOM or repeated GC and retries. In most real clusters 50 GB is too big to broadcast safely, so shuffle join wins, then you make it stable by pre-partitioning or bucketing by trip_id where feasible, tuning shuffle partitions, and enabling AQE to coalesce partitions.

Cloud Infrastructure
In practice, you’ll need to articulate why you’d pick Spark/Hive vs an MPP warehouse vs Cassandra for a specific workload. Interviewers look for pragmatic tradeoffs: throughput vs latency, partitioning/sharding choices, and operational constraints.
A the company warehouse for a client’s KPI dashboard has unpredictable concurrency, and monthly spend is spiking. What specific changes do you make to balance performance and cost, and what signals do you monitor to validate the change?
Sample Answer
The standard move is to right-size compute, enable auto-suspend and auto-resume, and separate workloads with different warehouses (ELT, BI, ad hoc). But here, concurrency matters because scaling up can be cheaper than scaling out if query runtime drops sharply, and scaling out can be required if queueing dominates. You should call out monitoring of queued time, warehouse load, query history, cache hit rates, and top cost drivers by user, role, and query pattern. You should also mention guardrails like resource monitors and workload isolation via roles and warehouse assignment.
You need near real-time order events (p95 under 5 seconds) for an Operations dashboard and also a durable replayable history for backfills, events are 20k per second at peak. How do you choose between Kinesis Data Streams plus Lambda versus Kinesis Firehose into S3 plus Glue, and what IAM, encryption, and monitoring controls do you put in place?
GS interviewers love to blur the line between "can you write the query" and "can you ship it reliably before the trading desk needs it." That compounding effect, where a SQL problem escalates into a pipeline design discussion grounded in GS's pre-market SLA pressure, is what separates this loop from a standard data engineering screen. The biggest prep trap is treating each topic as isolated when GS's Superday panelists explicitly build on each other's questions across sessions.

Competitive Moat
Goldman Sachs Asset Management oversaw approximately $3.5 trillion in assets under supervision as of September 30, 2025, and the firm is actively expanding its wealth channel through moves like co-branded model portfolios with T. Rowe Price. Cross-firm product launches like that require stitching together portfolio data, risk feeds, and client reference data across systems that weren't originally designed to talk to each other. That's the kind of integration problem GS data engineers solve daily.
The "why Goldman?" answer that actually works ties your skills to a specific initiative, not to the brand. Instead of gesturing at prestige, reference the T. Rowe Price partnership or GS's investment in open-source Scala tooling and explain why the data engineering challenge behind it excites you. Interviewers at GS are screening for people who understand that a data pipeline feeding a co-branded portfolio product has different SLA and lineage requirements than a generic analytics dashboard.

700+ ML coding problems with a live Python executor.
Practice in the EngineFrom what candidates report, GS leans heavily on SQL problems with a financial flavor, where understanding what the data represents (positions, P&L, client hierarchies) matters as much as getting the syntax right. Practice at datainterview.com/coding with that mindset: don't just solve the query, articulate why the business cares about the result.

1 / 10Can you design an ETL or ELT pipeline that handles incremental loads (CDC or watermarking), late arriving data, and idempotent retries?
GS's Superday panels score behavioral answers independently, so drill your STAR stories against Goldman-specific prompts at datainterview.com/questions until the delivery feels natural under fatigue.
Frequently Asked Questions
How long does the Goldman Sachs Data Engineer interview process take?
Expect roughly 4 to 8 weeks from application to offer. You'll typically start with a recruiter screen, then move to a technical phone screen, and finally an onsite (or virtual onsite) with multiple rounds. Goldman moves faster for experienced hires but can slow down during busy quarters. I've seen some candidates wait 2+ weeks between rounds, so don't panic if things go quiet.
What technical skills are tested in the Goldman Sachs Data Engineer interview?
SQL is non-negotiable. You'll also be tested on Python, distributed systems (Spark, Hadoop), and data pipeline design. Goldman cares a lot about data modeling, ETL architecture, and how you handle large-scale data workflows. Expect questions on cloud platforms like AWS or GCP, and be ready to talk about orchestration tools like Airflow. They want engineers who can build reliable, production-grade systems.
How should I tailor my resume for a Goldman Sachs Data Engineer role?
Lead with impact. Goldman values quantifiable results, so frame your experience around scale (rows processed, pipeline latency reduced, cost savings). Highlight any work with financial data or regulated environments since that resonates with their business. Keep it to one page if you have under 10 years of experience. And mention specific tools like Spark, Airflow, or Kafka by name rather than vague phrases like 'big data technologies.'
What is the total compensation for a Goldman Sachs Data Engineer?
For an analyst-level Data Engineer (entry to ~3 years), base salary typically ranges from $100K to $130K with a bonus that can push total comp to $130K to $170K. At the associate level (3 to 7 years), base is roughly $130K to $165K, with total comp reaching $180K to $250K including bonus. VP-level engineers can see total comp north of $300K. These numbers are for New York. Other offices may adjust slightly.
How do I prepare for the behavioral interview at Goldman Sachs for a Data Engineer position?
Goldman takes culture fit seriously. Their core values are Partnership, Client Service, Integrity, and Excellence, so frame your stories around those themes. Prepare 4 to 5 strong examples covering teamwork, conflict resolution, ownership of a technical project, and a time you delivered under pressure. They want to see that you can work across teams in a fast-paced financial environment, not just write good code.
How hard are the SQL and coding questions in the Goldman Sachs Data Engineer interview?
SQL questions are medium to hard. Expect multi-join queries, window functions, CTEs, and performance optimization scenarios. Python coding questions tend to be medium difficulty, focused on data manipulation and algorithm basics rather than competitive programming puzzles. I've seen candidates get tripped up on query optimization and indexing questions specifically. Practice at datainterview.com/questions to get a feel for the right difficulty level.
Are ML or statistics concepts tested in the Goldman Sachs Data Engineer interview?
This isn't a data science role, so you won't face deep ML theory. That said, Goldman may ask about basic statistics (distributions, aggregations, anomaly detection) and how you'd build pipelines that feed ML models. Understanding feature engineering workflows and how data engineers support model training and serving is a plus. You don't need to derive gradient descent, but knowing the data lifecycle around ML systems helps.
What format should I use to answer behavioral questions at Goldman Sachs?
Use the STAR format (Situation, Task, Action, Result) but keep it tight. Goldman interviewers are busy and direct, so don't spend two minutes on setup. Get to the action fast and always quantify the result. For example, 'I redesigned the pipeline, which cut processing time by 60% and saved $40K per quarter.' Practice being concise. Rambling is one of the most common mistakes I see.
What happens during the Goldman Sachs Data Engineer onsite interview?
The onsite typically has 3 to 5 rounds lasting about 45 minutes each. You'll face at least one SQL round, one system design or data architecture round, one Python coding round, and one or two behavioral rounds. Some panels include a hiring manager conversation focused on your past projects and how you think about data problems at scale. It's a long day, so pace yourself and bring energy to every round.
What business metrics or domain concepts should I know for a Goldman Sachs Data Engineer interview?
Goldman is a financial services firm with $59.4B in revenue, so understanding basic financial concepts helps. Know what trade data, risk metrics, P&L reporting, and regulatory data requirements look like at a high level. You don't need to be a quant, but showing awareness of how data pipelines support trading desks, compliance, and client reporting will set you apart from candidates who only talk about generic ETL.
What are the most common mistakes in the Goldman Sachs Data Engineer interview?
Three things I see repeatedly. First, candidates write SQL that works but is wildly inefficient, and Goldman cares about performance at scale. Second, people underestimate the behavioral rounds and wing them. Third, candidates fail to connect their technical work to business outcomes. Goldman's culture is results-oriented. Always tie your answers back to impact. Practice your end-to-end stories at datainterview.com/questions before the real thing.
How should I prepare for system design questions as a Goldman Sachs Data Engineer?
Focus on designing data pipelines, not web applications. Think batch vs. streaming architectures, data lake design, schema evolution, and fault tolerance. A common prompt might be 'Design a pipeline that ingests trade data in real time and serves it to downstream analytics.' Practice drawing clear diagrams, explaining tradeoffs (latency vs. throughput, cost vs. reliability), and calling out where you'd use tools like Kafka, Spark, or Airflow. Specificity wins over hand-waving.
