Round 1: 2-hour HackerRank challenge - fairly easy questions.

Round 2: Phone interview. Twice, I sat in front of my phone and laptop waiting for the interviewer to call, but I never got a call. Finally, when the interview was scheduled for the third time, I received the call.

• 10 mins: Resume discussion, why I want to work with Palantir, etc.
• 30 mins: Coding question
• 5 mins: Questions

Total interview duration: 45 mins.

I think I did a good job with the coding question. The interviewer seemed pleased with the solution. He didn't say if he felt something was wrong, odd, or missing.

Two days later, I got an automated email stating, "We can't continue with you as we have decided to move ahead with other candidates."

I would have appreciated it if, at least after wasting three hours, the recruiter could have sent a personal message. Now I am absolutely clueless about what went wrong in what seemed to be a very decent interview.
