Hackerank's medium difficulty problems (90 minutes) to solve before the screening call. Then the usual chat with HR recruiter. Later got invited to the 2 hours and 15 minutes interview with 3 developers. The interviewers were pleasant and made a lot of technical questions, from system design to Java/Spring, database query optimisation, choosing technologies and so on. Two out of three interviewers explicitly told me that they were satisfied, and the other one looked satisfied to me, but I got an email saying that I failed the interview with no feedback. Shame on me investing 4 hours interviewing
