I had 5 interviews for an internship position. One behavioral interview for 50 mins, then 3 times call back for 3 hours of technical interview with 3 project managers, They went pretty well and I've been able to answer all of the question and coding in a reasonable time. And then the last one for another technical interview, after that I have not heard about them any more, fortunately! I could say other than 2 of interviewers the others were impatient, along with the short notice interview request, where all of 5 interviews happened in around 7 days or less. For the last one, they sent me the request at 11:00 am for 1:00 pm interview the same day, in a way that either you do it or you will lose the job. I accept it, but after 10 mins of talking and considering impolite and impatient behaviour of the interviewer, I realized that this is not the type of people that I want to work with them, so intentionally I didn't answer two questions and end-up the call politely in less than 30 mins. They even have not send any decision letter or something similar to me. Considering the fact this was for an Internship position, these behaviours were completely unreasonable.
