Most of them do it because everybody else is doing it. Every time some poor soul gets tasked with interviewing candidates, he just fires up a google search to find good interview questions. He reads about puzzles, fizzbuzz and "analyzing your candidate's though process". And with nothing else in sight, he accepts them as the golden standard. The best part is that each and every one of these interviewers thinks they're special. Like they are somehow clever and intelligent by asking this type of questions. They don't even realize that they are using the same lazy approach everybody else is taking. The truth is, tech interviews revolve around your interviewer. How you make HIM feel. I've seen idiots get hired because they were enthusiastic. And extremely intelligent people rejected because "they couldn't communicate the way I like it". So in an interview forget about your skills, experience and anything else related to the job. It doesn't matter. Just woo the person across the table and you will get an offer. This works most of the time for shitty companies with lazy interviewers. And that's most of them. Personally, I found that that companies that allow this type of interviewing behavior will overwork and underpay you. Because they don't care. They just want to push things out to make a quick buck. If you want to be treated like an expert that has a brain in his skull, avoid them completely. Instead, find the companies that trust your experience. That act like you're as good as you say. And just make a quick check to see if you know what you're talking about. They are rare and most of them are startups. But the higher pay and better work environment is completely worth it.
