I had 5 calls in total and got rejected in the last stage. People, in general, were very friendly and I got a great impression of the company's culture. A few problems/negative comments: - I had TWO recruiter calls before having the first real interview. After the first recruiter call (I think they were a contractor), an interview was scheduled. I thought it was a real interview but it was yet another recruiter. A bit of a waste of time. - The last interview was a Product Sense interview. I got rejected because I didn't do well, it was fair. However, the case that was presented (and shared a few days before the interview) was about the Preply product. As someone who runs these interviews in my current company, I can say that it's not good practice to ask candidates to elaborate product cases about the company they are interviewing for - this biases the opinion of the interviewer. It's best to pick another product to talk about, so both people in the room are following the same thought process.
