It was an online interview where they asked me common questions, like "why do you want to work here" or "describe your past experiences". The interviewer was polite and friendly although I was not selected in the end

The first round of interview was with a recruiter, it went well and a couple of days later she emailed me that I got to the next round. The next round was a two piece assessment, which took 2 hours to complete. Literally a day later I got a rejection email stating that they already filled the position!?? Absolutely shocking behaviour and complete lack of respect for candidates’ time.
