I was "acquired" in a buy-out, not hired, so no interviews. Our interview process consisted of 3 separate interviews with different executives and managers asking the questions. Then if an offer was made, there might be negotiations, and finally a signing. Offers were standard with the only variable being the level of wage.

Question 1
You could get 5 minutes to prepare a 10 minute presentation for immediate presentation. It would typically be about something you are supposedly an expert on.
