Interview questions were average and I succeeded in all the rounds, they kept my application on hold for few weeks and then rejected, gods knows why! Really pissed off on them since my interviews went really great.

There were 4 rounds of interview

1. Technical coding and project based rounds(mainly around performance bottlenecks and C/C++)
2. Managerial round
3. Director round focused on cultural fit and day to day developer roles and challenges
4. Bar raiser : coding questions on their platform and theoretical question on tech stack and projects
