I know no end of people in the exact same bucket. I used to think I wasn't in the bucket at all as I've been through many difficult and time consuming interviews but I always got an offer until I interviewed at Microsoft and Google (though I still maintain my failure at those two companies were not entirely my fault but I digress).

After going through the march of those two big companies I found the process incredibly annoying and not useful at all; nothing of substance was really ever discussed it was almost always academic or some sort of trick question where I get to hear the interviewer talk for half an hour how they came up with a superior technique.

I've interviewed a lot of people. Interviewing software developers is such a pain in the ass.
