I got an invitation for a 1 hour interview with two of main decision makers, they showed a lot of interest and were so happy. However, after 2 months and after calling them the HR sent me a rejection, Unbelievable, and disrespectful!

3 rounds of interviews, each round with new members of the team. Each interview lasted roughly 30 minutes or so and consisted of both behavioral and technical questions. Typical interview/finance questions, nothing out of the ordinary.
