Lead Software Engineer Interview Experience - Singapore

January 20, 2026

Neutral ExperienceNo Offer

Process

I applied through a recruiter, and the process took two weeks.

There is no recruiter round, and the first round is coding. The interviewer gave a LeetCode question that was a 100% copy-paste from LeetCode with some given constraints. I went through the coding pretty well, but in the end, the interviewer said I missed the validation for the given constraints, which is usually not required.
