Not in my opinion no, and I don't mind people asking me simple questions either. There are quite a few people who simply don't understand basic concepts and cannot actually write code. Higher qualifications are usually weakly positively correlated with competence, but there are plenty of outliers and exceptions.

I do generally agree with the cargo cult sentiment, but not in this case.

The main thing I dislike about the 7+ interviews is that I dislike interviews and there are 7 of them to get through. I once did four in one day, back to back, and I was extremely tired afterwards. So my big fear as a candidate is that either 7 interviews will happen over 1-2 days and I'll be absolutely fried after the first 2, or they'll be so hard to schedule it'll take 6 months just to have them all. I'm also a bit afraid they'll cargo cult some of the interview questions and I get a bit sick of "please recite 1st year CS algorithm" questions (I never ask these personally) but otherwise 7 interviews is fine, if they accept I am a human candidate and I'm not really comfortable in the process anyway.
