This is surprisingly easy, but you have to understand what the problem is first or the solution won't be apparent. If this sounds patronizing it comes about from my frustration on being on the other side of the table too often. What you want is very good football (soccer) players. Unfortunately you (or upper management) may not know all of the rules to soccer. You may not know the training regime that goes into winning a good soccer game - and it's a big risk spending money training for the big game on the off-season only to lose during the Big Show. So what do you do to test potential candidates? You see if you can get along with them, if they're a team player, and then see how well they play foosball. It's perfect! There are soccer players on the field, there's a goal, it takes skill and coordination. But oh no, it turns out in the population at large really good soccer players really sort of suck at foosball. After all, they'd rather spend their time and energy playing soccer. So now they spend all their time reading up on books about foosball and what the best foosball strategies are. You see where I'm going with this? No one uses algorithms in their day jobs. OK a few of you, but come on man, I make full stack web applications. As do most programmers. So why are you testing theory that has literally nothing to do with the job? Somehow someone thought this was a proxy for smart people, but I mean, if the guy who wrote this "Tech Interview Handbook" was really smart wouldn't he have spent his time writing a cool program? I mean how lame is this? If you want to hire competent engineers tell them what you're building and ask them how they feel is best for them to show they're competent. If you have a big data pipeline in Scala ask if they can construct a data pipeline example that is cool over a few days (take home) or do something similar in the office. Some people like one, some like the other. But just communicate with the people you want to hire! And if not everyone's interview process is the same then maybe that's ok. I mean I just got a guy who sent me some automated code interview program that had a timer that counted down from an hour at the top! WHO THINKS TREATING THEIR POTENTIAL EMPLOYEES LIKE STAR WARS DRONES IS A GOOD THING? All you have to do is treat the people you want to work with like you would want to be treated and demand that they know their shit. This. Isn't. That. Hard.
