Practice problems
Shopify senior data engineer practice set
Shopify senior data engineer practice set, mapped from predicted domain emphasis. Tap into any problem to work it in the live environment.
Smooth Latency
Some of our API endpoints look like they are drifting slower as traffic grows, and we want the underlying trend rather than the per-call noise. For each endpoint, walk its calls from oldest to newest (breaking ties by call_id) and, at each call, report the average latency across that call and every earlier one, skipping any call with no recorded latency.
The Overlap
Your monitoring system logs server maintenance as `[start, end]` minute ranges, and windows that overlap or sit back-to-back really describe one continuous outage. Collapse the `windows` so any that overlap or touch at an endpoint become a single range, and return them ordered by start time. Two windows touch when one ends exactly where the next begins.
The Queue That Wouldn't Stop Growing
Your streaming video event pipeline shows consumer lag spiking from near-zero to over 500,000 messages within two hours. You need to diagnose whether the cause is a producer burst or a consumer slowdown, then design a monitoring and auto-remediation system that can detect, alert on, and automatically recover from future lag events.
The Runner-Up
Return the second-largest distinct value in the input list of integers. If the list has fewer than two distinct values, return `None`.
Walk into Shopify knowing the system design pattern they'll test.
Daily signup-to-purchase funnel
Count signups and first-time purchases per day. Product-company favorite.

Marker in hand. Draw the whole thing.

The loop
How the interview actually runs
01Life Story
45 minShopify's famous opening round. Not technical, not quite behavioral. A deep career-narrative conversation. The interviewer wants to understand how you think about your own trajectory.
- →This is not optional chit-chat; it's evaluated
- →Prepare a chronological career narrative with reasoning for each pivot
- →Shopify looks for self-awareness and intentionality
02Technical phone screen
60 minSQL + a pair-programming session. Focus is on practical e-commerce analytics: conversion funnels, merchant revenue, cart abandonment.
- →Practice funnel analysis SQL
- →Know e-commerce vocabulary: GMV, AOV, session, conversion, attribution
- →Shopify uses GraphQL heavily; API-data familiarity helps
03Pair programming
60 minLive collaborative coding session. Usually a small project that demonstrates how you think, ask questions, and iterate.
- →Think out loud
- →Ask clarifying questions early
- →Shopify values craft; don't rush to a wrong answer
04System design (pipeline architecture)
60 minDesign a production pipeline end-to-end: ingestion, transformation, storage, consumers, SLAs, failure modes, backfill strategy, and cost trade-offs. At senior level, you drive the conversation without prompting. Expect follow-ups about scale, cross-team coordination, and operational load.
- →Anchor on the SLA and data shape before diagramming
- →Discuss idempotency, partitioning, and backfill explicitly
- →Estimate cost: 'This pipeline will cost roughly $X/month at this volume'
05Onsite: architecture + values
60 minBlended technical + behavioral. Shopify's 'Make Great Mistakes' value is genuine; they want thoughtful ambition.
- →Rails and Shopify's internal frameworks are fair game
- →Merchant-first framing beats tech-first
- →Remote-first engineering practices are a real conversation
Level bar
What Shopify expects at L5 Senior Data Engineer
Independent technical leadership
Senior DEs drive pipeline designs without engineering manager involvement. Interviewers probe whether you can decompose ambiguous requirements, make architecture trade-offs, and defend your choices under scrutiny.
Cross-team coordination
Senior scope regularly spans multiple teams. Expect scenarios about a downstream team missing an SLA because of a change you made, or negotiating a schema migration with the team that owns the upstream source.
Production operational rigor
Fluent in on-call, alerting, data quality checks, and incident response. Dive-deep stories at this level should include correlating a metric drop to a specific commit or a timezone bug or a subtle ordering issue, not 'I looked at the logs.'
Shopify-specific emphasis
Shopify's loop is characterized by: Merchant-first e-commerce scale with digital-first remote engineering culture. Calibrate your preparation to that, generic FAANG prep will not close the gap on company-specific expectations.
Behavioral
How Shopify frames behavioral rounds
Be a constant learner
Shopify's Life Story round is structured to detect learners.
Get shit done
Shopify ships fast. Theorists without delivery records don't fit.
Be a merchant advocate
Shopify measures success in merchant success. Every engineer connects to it.
Thrive on change
Shopify reorgs often, tools change often, remote life requires adaptability.
Prep timeline
Week-by-week preparation plan
Foundations and gap analysis
- ·Do 10 medium SQL problems. Note which patterns feel slow
- ·Write out 2-3 behavioral stories per value, Shopify weights this round heavily
- ·Read Shopify's public engineering blog for recent architecture patterns
- ·Review your prior production work, pick 3-5 projects you can discuss in depth
SQL and coding fluency
- ·Practice window functions until DENSE_RANK, ROW_NUMBER, LAG, LEAD are reflex
- ·Do 20+ Shopify-style problems in their domain
- ·Time yourself: 25 min per medium, 35 min per hard
- ·Record yourself narrating your approach aloud. Interviewers weigh how you explain it, not only what you write
Pipeline system design
- ·Design 5 pipelines on paper: daily aggregation, clickstream, CDC, ML feature store, real-time alerting
- ·For each, write SLA, partition strategy, backfill plan, and cost estimate
- ·Practice with a friend, senior-level system design is 50% driving the conversation
- ·Review Shopify's open-source and engineering blog for in-house patterns
Behavioral polish and mock loops
- ·Rehearse every story out loud. Cut to 2-3 minutes each
- ·Run 2 full mock loops with a senior DE or coach
- ·Identify your 3 weakest behavioral areas and draft additional stories
- ·Review recent Shopify news or earnings call for fresh talking points
Taper and logistics
- ·No new content. Review your notes only
- ·Sleep. Mental energy matters more than one more practice problem
- ·Confirm logistics: laptop charged, shared-doc tool tested, snack and water nearby
- ·Remember: the loop is rooting for you to raise the bar, not to fail
