RH Operations Manager interview questions

Was reminded 20 times that they take you through 15 interviews...to make sure your the right candidate. You would think someone would grow a set and just make a decision. It was long and dragged out, and quite a big waste of time. On a side note, the culture of the company in my opinion is highly questionable. Their CEO sent some ridiculous email earlier this year to all his employees threatening to fire them. He seems erratic and briefly stepped down a few years ago for inappropriate relations with a employee. Also, they must be in dire straits as their stock has fell this year alone from their high at $106 to $25, which has now settled around $30. That's a 70% decrease. It seems like volatile company with an erratic CEO, they probably did me a favor by not going forward after they 4th interview.
