PineLabs Software Engineer Interview Experience
Software Engineer
Summary
AI Powered
The interview experience at PineLabs consisted of two rounds, focusing primarily on coding and database concepts. In Round 1, candidates encountered medium level questions related to stack operations, greedy algorithms, and dynamic programming. The second round included discussions on database management, SQL queries, and further DSA problems. Overall, the interview process was moderately challenging and sought to assess both technical skills and theoretical knowledge relevant to the roles at PineLabs.
