I was invited to a half day interview containing three separate interviews. It's basically a one and done process. The scheduling was an absolute disaster. They reached out to me at the end of January. I responded the same day with everything they needed. They never responded, even when I responded to the same email chain twice asking about the status. Three weeks later, the same recruiter sent me the same canned email as if he had never met me. I responded the same day again. Two days later, he responded and asked if I could interview two days later for a half day interview. I was on vacation overseas and said I could make it work, but I would really appreciate it if they could accommodate the following Monday. He got back to me a day or two later and said the next Tuesday was fine. The day before the interview, he asked for a pre-interview call. I got on with him, and he told me I hadn't responded quickly enough to their requests and they weren't able to interview me afterall! I had already spent 6 hours preparing for the interview, which was supposed to be the next day. I had also wasted three partial vacation days responding to their requests for documentation. I complained, and surprisingly, someone heard it. They reassigned a new recruiter (but who knows what my chances were at this point) and offered me an interview even though interviews were already over. The interview was ultimately unsuccessful, but I felt like it was all making motions at that point anyway. On my end, showing up was basically just to get experience.
