I had two interviews: * One with HR. * A technical one, where I was asked to solve a problem in a blank shared document with the interviewer.

I was summoned, but the interview itself never happened. I didn't receive any further information after that, I waited, and I refused another offer in the hope of being called again.

The interviewing process was extremely long (6 months), and there was almost no feedback about my candidacy status. I thought that I was discarded during the process, but I actually got an offer, and they refused to negotiate.
