FireEye interview questions

I wan initially interviewed for Senior position. Then after the "Googlnes" interview (Very stupid questions that have nothing related to the actual job) they changed it to a non-senior position without telling me. I found out by chance and the HR asked me to do the final interview which will be where they sill "decide" if it is senior or not, like it is not my choose too :). The offered me the non-senior position and I declined it. The process was the worst, I have four interview and non of them were hilt on the aggreged time, all of them were rescheduled at some point, sometime even couple of hours before the interview. This really shows how unprofessional they are.
