Onsite Coding (Applied)
One classic DS&A round and one applied/real-world round
What this round is judged on
- Problem decomposition · breaks the task into clean pieces
- Pragmatic design · sensible data-structure and API choices
- Adaptability · absorbs new requirements without rewrites
- Readable code · maintainable, not clever-for-its-own-sake
- Communication · reasons out loud through trade-offs

What happens in each stage›
- Recruiter / hiring-manager screen
- ~30 min spoken, non-technical: motivation, background, logistics, level calibration.
- Technical phone screen (coding)
- ~45-60 min live coding in a shared editor (CoderPad-style); 1-2 practical DS&A problems; gate to the onsite.
- Virtual onsite loop
- Typically 4-5 back-to-back rounds: roughly 2 coding (one DS&A, one applied/build-a-small-thing), 1 system design (weighted for E4+, lighter/omitted for new-grad E3), 1 behavioral/values, sometimes a debugging/work-sample or domain round.
- Hiring committee / debrief
- Committee-style review, then offer and level (ladder E3-E7).
