Took roughly 2 months total. Recruiter was very fast to respond and the interviewers were all very nice and collaborative during the interview. Typical HR call, two technical rounds, and behavorial round.
Live coding #1 focuses on algorithms and data structures, testing problem-solving skills and efficiency. Live coding #2 emphasizes coding challenges and practical problem-solving. The behavioral round assesses experience, teamwork, and culture fit.
