alt Hacker NewsPeople are sheep. Someone somewhere used mathematical puzzles as interview questions. That someone became big. Others assumed it was because their interview process was amazing and followed blindly. Soon enough the process started to be gamed.
I'm seeing this trend again in the field of AI where math olympiad participants are being given God like status by a few companies and the media.
Truth is even the most prolific computational scientists will flunk these idiotic interviews.

I am guilty of this. I started asking simple programming questions back in the early 90s. It was just a way to see if interviewee knew how to use for loops and conditionals, to see if they can solve simple problems. It was great when taken unprepared, but once people started drilling and memorizing them, the problems became a lot harder. It got to the point where you really have to study, it is not enough to have 20 years of professional programming experience.
Fun story. For years, I used a set of problems that I took from a very old programming book. I have probably seen dozens of solutions for these problems. About 6 years, in an interview, somebody happen to ask me about one of these problems. So, I wrote the solution and the interviewer told me it was wrong, but he couldn't tell me why it was wrong. Then he proceded to clean the screen. (It was remote interview). So I flunk the interview with a problem that I knew back and forth.
Yes, and it's mostly the fault of a handful of companies like Google and Facebook that were started by founders who were still in college, so choose interview problems that look like CS algo puzzles instead of anything related to real work.
Hundred percent. Classic example of academic smarts vs real world smarts.
It's why developers as a group will lose negotiating power over time. You would expect a smart person to question why that 'problem' exists in the first place rather than forge ahead and making a solution for a problem that doesn't exist. It's like your manager telling you to write a software that does something, whatever that is. Your first question should be why and you should not type a single letter until you understand the domain and whether a software solution is needed in the first place.
For all the intellectuality modern devs give to themselves, they are still asking how high when told to jump. And in some cases even bragging about jump heights. Only difference is that many devs look down upon others (or simply are unable to understand those) who refuse to jump.
We all know devs have better things to focus on, given the state of modern software development.
