Usually this is false. Startups are some of the most aggressive users of whiteboard trivia, live coding, etc., to filter out candidates who don’t fit precisely the mold of people desperate to work at FAANG companies.

They don't hire you on a resume, you need to demonstrate skills. Wether it's a good way to do so is another matter.
I had interviews with startup not even asking for my resume, or testing my skills. But I never had a startup getting me through many hoops in the hiring process. 4 steps over a few months was the max, while FAANGs are known for using more than 10 steps, dispatched over as long as a year.
