Did their 4-9 hour(!) mandatory take home coding test. Never done such a terrible test in my life; in every way they made a test akin to basically locking a c++ dev in a room for anywhere between 4-9 hours and afterwards rolling a die. Its underspecified, but then has automated tests, that, after failing twice, automatically reject you as a candidate. Of course it doesnt give examples or example test cases or real test cases, so you're shit outta luck trying to solve it. The challenge itself would be fun and solvable in 4 hours, but around the 2 hour mark you start having questions and from there its just bad. You can google this coding test ("think-cell interval_map") and youll get a lot more info. I complained to them just in case they cared, and they did seem to care, but failing to specify an automatically tested coding challenge is the kind of psycho shit you do if you think youre the smartest guy in the room (but arent). ETA: To be clear, I stopped the second I realized it was an underspecified test. I'm not that mad, just mad I fell for spending a whole saturday morning doing it, without ever talking to anyone there in a call or anything. That and the fact that theyre just building a powerpoint plugin and seem to overcomplicate it to such a massive degree: Yeah no thanks.
