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 IMC Trading interview outcomes, avoid these common traps:
- Suggesting generic tools without explaining how to reproduce the load
- Failing to account for the cooldown period
- Using a simple sorted list which leads to O(n) insertion
- Failing to mention how you measured the improvement
