SWE New Grad Interview Experience - New York, New York
February 25, 2026
Positive ExperienceNo Offer
Process
The process took 1 day.
- Algorithmic clarity: Can you identify the core pattern quickly? Think: prefix sums, sliding windows, graph traversal, greedy with proof, DP state design.
- Mathematical reasoning: They love problems where correctness requires a proof or invariant. Example: why a greedy choice works, why a hash remainder trick detects divisibility.
- Performance instincts: You are expected to reason about:
- Time complexity under constraints
- Memory vs speed tradeoffs
- Edge cases at scale (10⁶–10⁹ inputs) This is finance engineering. Latency is money.
Questions
- Prefix sum + hashing
Why? O(1) lookups under heavy data flow.
Examples:
- Subarray sum divisible by k
- Longest equal 0/1 subarray
- Detect arbitrage-like patterns
What they care about: Do you understand why equal remainders imply divisible differences?
