The equipal Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3

Round 4
Onsite CodingLeetCode-hard, debugging, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of equipal interview outcomes, avoid these common traps:
- Using a simple sort on a list for each median calculation, leading to poor performance.
- Incorrectly handling timestamp comparisons or window boundaries.
- Inadequate error code definitions or messages.
- Calculating percentage change incorrectly (e.g., using absolute difference instead of relative).
