Robinhood · Software Engineer (New Grad)
Robinhood's new-grad loop is a fintech-flavored gauntlet: an OA, a couple of algorithm rounds, and often a practical or debugging round that leans on correctness because the product executes real trades. Interviewers care that your code is right and defensible, not just that it passes the happy path — off-by-one errors on money or ordering are costly. A behavioral round probes ownership, safety-mindedness, and how you handle high-stakes, time-sensitive systems.

What this interview tests
- Algorithms & data structures (arrays, hash maps, trees, intervals)
- Financial correctness (rounding, integer cents, no float money)
- Handling duplicate / out-of-order events in a stream
- Practical coding and methodical debugging
- Edge-case and boundary reasoning under high stakes
- Ownership and a safety-first mindset (behavioral)
Common question themes
Process a market-data / order stream with duplicates
Interval and scheduling problems (merge, overlap)
"How do you avoid rounding errors when handling money?"
Debug a failing test in an unfamiliar service
Hash-map and two-pointer array problems
"Tell me about a time you caught a bug before it shipped"
