Went through 8-9 interviews, from technical to behavioral to executives'. single and panel. Some were keen on finding one word or one phrase that I slip answering, and it happened. I had to go through 2 interviews with the same employee.

The standard way; applied online, was contacted with some basic questions and info. The HR person was very professional ; I found however the COO rather incompetent, not focused and not able to respond clearly to my simple question and seems she felt intimidated by them.
