On the record I’ll say the average person interviews below their ability and if you can interview at your ability you are practically doing better than your ability.

This might look a little “scammy” but I’ll vouch that Bob Firestone changed my viewpoint of job interviews completely

His course took me from being terrified of job interviews to being willing to do them for fun or just to find out what is going on in an organization.

There is another approach to interviewing where you look at it as a flawed process (it’s like they are trying to reject people instead of hire people) and try to subvert it in a gentle way. There are quite a few ways to do this but one of the best is to put on the mindset of a consultant and try to help with the problem the company has right there in the interview, that is, you ask questions to that end every chance you can get like a coiled spring.

Now that doesn’t work in a FAANG company because the people who designed these processes are looking for round pegs to go into round holes and know that a person with highly developed narcissism can cheat their way around that kind of organization so the highly structured interview process prevents anyone from exploiting “weak points”. (Once a narcissist gets in they will wield OKRs, stack ranking and similar practices as a weapon against anyone; a person who can convince their superiors that their glass is half full and yours is half empty will rise quickly to the top which is why having a founder as CEO is actually healthy for that kind of organization.)

The good news is that most employers aren’t FAANGs. The bad news is that a FAANG history is not going to help you succeed anywhere, see

for a basic criticism of that kind of environment and why being a senior in that organization qualifies you as a junior in any other organization. So in some way you are going to have to accept a step down and some crawling back up.

Good luck!
