I got the invite to interview via LinkedIn.

First, I had a phone call about my experience and development goals.

After that, I got an invite to an onsite interview. There, I had 3 stages, each 1 hour.

First was a technical interview, with typical iOS questions and some about concurrency. I responded to questions about Swift, but I failed on questions about Objective-C and concurrency.

Second stage was pair programming, where I had to implement a simple algorithmic task. The interviewer had mixed feelings about my solution.

Last stage was about motivation, goals, and development.

I got invited for a last phase, which was a phone call with one of the company founders. There, I got more questions about organizing my time, motivation, etc.

After that call, I was rejected.

Every phase, the response from the company was late.

What is a deadlock?
