I had interviewed 4 separate occasions with 6 people. While it wasn't particularly difficult it seemed excessive. I did explain that I was currently working and had limited availability. At the end I had to accept the role as I had zero sick/vacation time available. They proceeded on having a grueling background check with an Indian company "HireRight" who demanded W2s for each position. I am only thankful that I didn't have to submit to a proctology exam as I had provided everything else. I wouldn't bother interviewing with them again for a CEO position.
