I was called for 2 potions by HR. Then I had 5 rounds and nothing was clear from the start. It was very add hoc process. They were very unresponsive and unprofessional. No structure no feedback, they do not keep you in the loop. Extremely frustrating. The process took 4 months and I never new when the next stage is going to be. Usually takes about 2 weeks in between. Also, there was very little flexibility in terms of schedule
