Technical Coding Behavioral
There were supposed to be 5 rounds in total, each 45 minutes long. But sometimes they merge the last 4 rounds into one if a panel is free. In my case, only 4 rounds happened. Before interviews, I got a 30-minute assessment with one basic DSA question and multiple-choice questions on JS, React, and Angular. The recruiter said at least 3 out of 5 rounds needed to be positive. Based on interviewers' feedback, I think Rounds 1, 3, and 4 went well out of the 4 that occurred. After the 4th interview, the recruiter ghosted me. The 5th round didn't happen, and they stopped replying to calls or emails. Very unprofessional.
