The interview process was in 3 stages. The first interview was with a recruiter lasted for 15-20 mins. After a week, recruiter scheduled an interview with a director. The phone interview lasted for 30 mins. It was positive, good discussion. I didn't hear anything back for 3-4 weeks, and then suddenly recruiter reached out saying they would like schedule another phone interview with a manager for 30 mins. The phone interview went well again, the manager asked me more technical questions and for 10 mins, I was given a case study, which we were discussing from multiple angles. I was asking questions, providing my inputs etc. I felt it went great. I was waiting for response from recruiter after this, never heard back. Not exactly sure, what are they looking for?
