The interviewer didn't join the call. It's very pathetic that we spend our time and interviewer don't even join the call. The interviewer won't even respond to our emails or messages. The hiring team won't respond to our emails.

Classic multi-step process starting with a phone call from a recruiter, then an HR chat in person combined with a technical test using a computer, and then later on an interview with a team manager and a head of the department.
