I had a problem with the recruiter not responding after the invitation for the onsite. They finally responded a few days before the onsite, but they reserved my hotel for only one day. Consequently, I had to sleep at the airport because my flight wasn't scheduled that late.

I had five interviews. The interview questions were too mathematical, with solutions that were too vague. Even when providing the correct solution, sometimes the interviewers had something else in mind, and you had to guess their intended answer. The interviewers were terrible.
