I had 6 interviews, 3 remotely (first with HR and then 2 with business oriented persons), and then 3 physically in their headquarter which were more technical. The first 5 interviews were really great and matched well, the people were nice and interested by me, but the last one with the final manager was awful. A guy not smiling at all who looked forced to be there, asking questions with a huge lack of details, not helping but expecting precise answers impossible to give without knowing their environment, and with a haughty behavior. Obviously due to the last interview, I didn't join the company.
