The Water Collector

Given a list of non-negative integers representing wall heights, find two walls (by index) that together with the x-axis form a container holding the maximum amount of water. Water volume between walls at i and j is min(heights[i], heights[j]) * (j - i). Return that maximum volume.

The loop

How the interview actually runs

01Recruiter screen

30 min

Pinterest's product is visual inspiration. DE work splits across Ads, Home Feed ranking, Creator, Shopping, and Trust & Safety.

→Know Pinterest's product vocabulary: Pin, Board, Save, Repin, Close-up
→Recommendation-system experience helps for Feed roles
→Pinterest's scale is smaller than Meta but similar shape

02Technical phone screen

60 min

SQL with engagement data: session analysis, Pin-save rates, board-completion metrics.

→Funnel SQL: impression → click → save → buy
→Cohort retention is a recurring theme
→Pinterest uses AWS + Presto + Druid heavily

03Onsite: data architecture

60 min

Design a pipeline for Pinterest: Home Feed ranking features, Ads attribution, shopping catalog integration, Trust & Safety flagging.

→Feature-store design for recommendation is central
→Real-time vs batch tradeoffs matter
→Druid is Pinterest's OLAP of choice; familiarity is a plus

04Architecture strategy

60 min

At staff level, system design expands to multi-system strategy: 'Design the data platform for a 500-person org' or 'We have 40 pipelines producing inconsistent output; how do you fix it?' The evaluator watches for whether you think about developer experience, tech-debt paydown, and multi-quarter roadmaps.

→Talk about teams and processes, not just technology
→Name the specific mechanisms you would create (code review standards, shared libraries, data contracts)
→Be ready to defend why not to build something you would build at senior level

05Onsite: behavioral

45 min

Pinterest's culture emphasizes thoughtfulness, inclusion, and creator empathy. Stories about polish and user impact land well.

→Creator empathy distinguishes Pinterest from pure ad platforms
→Slow, considered work is valued over blitz-shipping
→Inclusion is a genuine cultural pillar

Level bar

What Pinterest expects at Staff Data Engineer

Technical strategy ownership

Staff DEs set technical direction for multiple teams. Interviewers ask 'What tech decisions have you influenced across your org?' and probe depth: how did you socialize it, who pushed back, what trade-offs did you accept?

Multi-system design

Staff-level design is not one pipeline; it is the platform that 10 pipelines run on. Think data contracts, metadata stores, standardized ingestion patterns, shared orchestration, and the tradeoffs between standardization and team autonomy.

Tech-debt and migration leadership

Stories about leading a multi-quarter migration: the plan, the phasing, the stakeholder management, the rollback criteria. Staff DEs are expected to have shipped at least one such effort.

Mentorship scale

At staff, mentorship goes beyond 1:1 coaching: you have influenced hiring rubrics, run tech talks, or built onboarding that accelerated new hires.

Pinterest-specific emphasis

Pinterest's loop is characterized by: Visual-discovery platform with inspiration-driven engineering and careful, thoughtful culture. Calibrate your preparation to that, generic FAANG prep will not close the gap on company-specific expectations.

Behavioral

How Pinterest frames behavioral rounds

Put Pinners first

Pinterest's user-obsession framing. Engineers who frame work in user-impact terms resonate.

“How has a Pinner (user) observation changed your work?”

Aim for extraordinary

Pinterest rewards craft and polish. Half-done work stands out negatively.

“What's a piece of engineering polish you insisted on?”

Create belonging

Pinterest's inclusion commitment is real. Hiring panels evaluate this genuinely.

“How have you made a team more inclusive?”

Own it

Pinterest engineers are expected to drive work end-to-end with judgment.

“Describe an initiative you drove without explicit authority.”
