Behavioral was honestly the most laid back part of the whole thing. Recruiter reached out first, 20 min call. Karat had a medium array problem and a follow up on edge cases. Final round was 3 sessions: OOP design for a data store, a graph DSA question then behavioral on how I learn new tech

Questions Asked

  1. 1.Given a binary search tree, find the kth smallest element
