Hey everyone,
I have my first-round interview with Heisel for an FD role, and the recruiter specifically mentioned that it will be a 30-minute LLD (Low-Level Design) round.
If anyone has appeared for this interview before or has experience with Heisel’s interview process, could you please share:
What kind of LLD questions are usually asked?
Is it more object-oriented design focused or machine-coding style?
What level of depth is expected in a 30-minute round?
Any commonly asked design problems or topics I should prepare?
Would really appreciate any insights or preparation tips. Thanks!
