>> In most cases when a company rejects you because of "culture fit", chances are there's something wrong with yourself.

I completely disagree. Interviewing teams reject candidates for all sorts of reasons that have nothing to do the candidate.

Reasons (valid or not) a applicant gets reject include:

- thinking candidate would get bored in a menial job

- discrimination

- unstated hiring freeze

- position is closed during hiring process

- position requirements are revised

- candidate wants to pair program, company does not, and vice versa

- interpersonal communication challenges, mostly around language barriers

- candidate seems too expensive

- candidate seems way too cheap, which seems too good to be true

- company believes candidate will not tolerate commute for extended period of time

- candidate bugged recruiter one too many times about status of interview process

- candidate overdressed for interview

- candidate underdressed for interview

- candidate reminds an interview too much of themself ("I'm the vision person, and we need some who likes to build the plan I come up with")

- the job is a demanding grind, and everyone who previously had kids has quit

- company doesn't like candidates education

- company worked for a stigmatized employer

- a backdoor reference check doesn't go well

This list could go one forever, and none of these things are something wrong with the candidate.
