Top Batch Job Under Priority 1
Among batch jobs with priority equal to 1, find the job(s) with the highest rows_done value. If multiple jobs tie at that value, return all of them. Show the job id, job name, and rows_done.
The Coin Vault
Given a target amount and a list of coin denominations, return the minimum coins needed using a greedy strategy: repeatedly take the largest coin that does not exceed the remaining amount. Return -1 if the greedy approach cannot make exact change.
Event Ticketing System Data Model
We run an IT helpdesk platform. Users submit support tickets, which are assigned to agents. Tickets go through multiple status changes before being resolved. SLA compliance is critical: P1 tickets must be resolved within 4 hours, P2 within 24 hours. Design the schema, and describe how you would load data from a JSON API feed into it.
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 loop
How the interview actually runs
01Recruiter screen
30 minDoorDash operates at marketplace + logistics scale. Track splits: Consumer, Merchant, Dasher (driver), Logistics, Ads, International.
- →Three-sided marketplace (consumer, merchant, dasher) — acknowledge the complexity
- →Logistics teams are the most data-intensive
- →DoorDash ships fast; Amazon/Uber-comparable velocity
02Technical phone screen
60 minSQL + Python with marketplace + logistics data. Order funnels, dasher earnings, restaurant performance, delivery time analysis.
- →Marketplace matching SQL (assigning orders to dashers) appears
- →Time-window calculations (estimated delivery time vs actual) are common
- →Know three-sided-marketplace metrics: take-rate, fill-rate, contribution margin
03Onsite: marketplace design
60 minDesign a pipeline for a marketplace or logistics problem: ETA prediction, surge pricing, dasher routing, merchant analytics.
- →Real-time is central; batch is backup
- →Geospatial data (H3 hexagons, route optimization) is fair game
- →Discuss marketplace incentive design alongside technical design
04Onsite: behavioral + fit
45 minDoorDash's culture is high-velocity, operator-minded, and quantitative. Stories about moving fast and measuring everything land well.
- →DoorDash's 'One DoorDash' framing — stories about cross-team wins
- →Acknowledge dasher/consumer/merchant tradeoffs explicitly
- →Avoid stories about slow, methodical work
Level bar
What DoorDash expects at Data Engineer
Pipeline ownership
Mid-level DEs own pipelines end-to-end. Interviewers expect stories about designing, deploying, and maintaining a data pipeline that has been in production for 6+ months.
SQL + Python or Spark fluency
SQL is the floor. Most teams also expect fluency in either Python for data manipulation (pandas, airflow DAGs) or Spark for larger-scale processing.
On-call debugging
You should have concrete stories about production incidents: what alert fired, how you diagnosed, what you fixed, and what post-mortem action you owned.
DoorDash-specific emphasis
DoorDash's loop is characterized by: Marketplace logistics with last-mile optimization and fast-paced consumer engineering. Calibrate your preparation to that, generic FAANG prep will not close the gap on company-specific expectations.
Behavioral
How DoorDash frames behavioral rounds
Make room to grow
DoorDash's culture explicitly rewards career ambition and skill-stretching.
Seek truth, speak candidly
DoorDash values direct communication even when uncomfortable.
Think outside the room
Marketplace engineering requires thinking about unseen stakeholders (dashers, customers, restaurants).
Take smart risks
DoorDash's growth came from calculated bets. They want calibrated risk-taking.
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, DoorDash weights this round heavily
- ·Read DoorDash'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+ DoorDash-style problems in their domain
- ·Time yourself: 25 min per medium, 35 min per hard
- ·Record yourself narrating approach aloud, communication is graded
Pipeline awareness and behavioral depth
- ·Review pipeline architecture basics: idempotency, partitioning, backfill
- ·Practice explaining a pipeline you've worked on end-to-end in 5 minutes
- ·Refine behavioral stories based on mock feedback
- ·Do 10 more SQL problems at medium difficulty
Behavioral polish and mock loops
- ·Rehearse every story out loud. Cut to 2-3 minutes each
- ·Run 2 full mock loops with a mid-level DE or coach
- ·Identify your 3 weakest behavioral areas and draft additional stories
- ·Review recent DoorDash 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: interviewers want to find reasons to hire you, not to reject you
