1. Codility was a hard math question, which was weird and I thought I didn't pass, but I did. 2. Technical interview with an engineering manager and a senior manager from Japan. Overall it was very easy and only one easy leetcode question was asked. I solved it very fast and the managers seemed satisfied. 3. Behavioural interview with another engineering manager. No technical questions, and was asked about some questions on my tech interest, leadership experiences, etc. Overall was easy and the interviewer seemed to like me. I found it surprising that I was rejected in the end and when I asked for feedback, there was only positive feedback and no negative feedback. I am guessing it is due to some headcount or visa eligibility issue since this position is based in Singapore and I am applying as a foreign worker. Not sure about this tho.
