The first interview caught me a little off guard. It was a group interview with the VP of Sales and 4 other candidates. I don't have a problem with group interviews, but no one throughout the recruiting process communicated that to me at any point. That said, probably no one would show up if they thought they were coming in for cattle call. The interview itself was actually fun. And informative. Most 1st interviews are with some "hiring manager" or HR Recruiter who is more interested in asking form questions out of a book, than get to know me. Check the box. This guy gave a Power Point Presentation that showed the company, its history and future growth plans and went over the interview, hiring, training and comp plan. Very thorough. About two hours.
The second interview was very interesting and very long. They had me come in for assessment testing (again, no problem), interview with the Sales Manager who would be my boss, and then went on a ride along. I was very impressed. Most sales organizations want to know two things: Do you have a pulse and when can you start.
The final interview I have learned is only a formailty where the CEO hires you, reviews his core values, the comp plan and welcomes you aboard.
