App Stability by Region
The mobile team is weighing the next rollout and wants to see where the app keeps falling over. Looking only at app opens and crashes, count each for every tag set and event timestamp, and report the crash rate as crashes divided by opens, rounded to four decimal places.
Above the Title
You have three exports from a film catalog: `movies` (each with a `movie_id`, `genre`, `rating`, and `box_office`), `actors` (each with an `actor_id` and `name`), and `mapping`, the bridge rows that pair an `actor_id` with a `movie_id`. For a given `genre` and `min_rating`, return each actor's `name` mapped to the total `box_office` of the films they appeared in whose genre matches and whose rating is at least `min_rating`. Leave out any actor with no qualifying film.
Before the Rush
Ahead of the holiday planning cycle, the merchandising team needs to see how each product category's revenue shifts month to month. Show the total transaction amount for each category-month combination, ordered by category then month.
Chain of Command
Every employee's `manager_id` points to their manager's `employee_id`, except the CEO, whose `manager_id` is `NULL`. Return each employee with their depth beneath the CEO and the full chain of names from the CEO down, joined by / like a file path and listed in path order.

The loop
How the interview actually runs
01Recruiter screen
30 minVisa's DE work is concentrated in VisaNet (the payment network), Risk, and Visa Analytics. Culture is formal, deliberate, and global.
- →Know the card-payments ecosystem: issuer, acquirer, network, merchant
- →Risk and fraud roles are most data-intensive
- →Visa is less fast-paced than fintech unicorns; don't oversell velocity
02Technical phone screen
60 minSQL with payments data. Interchange, authorization, clearing, settlement. Scale is extreme (250B transactions/year).
- →Payments-flow knowledge is a real signal
- →Performance SQL (query plans, indexing) matters
- →Tokenization and security questions appear
03Onsite: data architecture
60 minDesign systems that feed Visa's network analytics, fraud models, or client reporting products.
- →Latency and throughput are first-order concerns
- →Global replication and failover is central to Visa's architecture
- →Discuss PCI-DSS and data-residency constraints
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: behavioral
45 minVisa's culture values deliberation and long-term thinking. Behavioral round probes how you handle ambiguity, failure, and multi-year timelines.
- →Long-running initiatives are standard; patience is valued
- →Quick-fix stories can land poorly
- →Global teamwork is a common theme
Level bar
What Visa 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.'
Visa-specific emphasis
Visa's loop is characterized by: Global-payments scale with network-reliability culture and emerging-markets focus. Calibrate your preparation to that, generic FAANG prep will not close the gap on company-specific expectations.
Behavioral
How Visa frames behavioral rounds
Trust and security
Visa's brand is trust. Engineers who cut corners on security fail fast.
Obsession with performance
VisaNet's SLA is extreme. Performance-consciousness is required.
Integrity
Payments integrity is non-negotiable. Interviewers notice hedging.
Empower our employees
Visa's culture value. Stories about mentorship and enabling others.
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, Visa weights this round heavily
- ·Read Visa'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+ Visa-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 Visa'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 Visa 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
