It was a tedious and frustrating process, involving six rounds of interviews, including two with the same recruiter. According to the process, every interview needed to be satisfactory to move onto the next one. Ironically, the last round was scheduled three weeks later, during the time I had received an offer from another firm. So, I politely asked if they would be willing to reschedule the last round a bit earlier. After receiving no response, I eventually decided to drop out and accepted the other firm's offer.

I still do not understand why they have such an excessive amount of interviews where all questions are pretty much the same.

Very bad experience; I never want to go back to them again.

All the usual questions and lack of intelligence.
