They were late for every interview session. 5-15 mins. One of them were shifted. + They claim the wrong dates when they will give a feeedback. After the first interview they said I solved programming task very well, and that I can relax with the following interviews sessions, because I'm gonna be a great addition to the team. I passed all 3 interviews and after a week they sent me an email saying that despite my outstanding programming skills they have found someone better.
