There are other sites that do this and they generally just drop these exercises without warning on candidates without even telling them what stack it is. I got asked to do a MERN coding exercise when I haven't touched that stack for years. I expect this app will be used the same way. It's just a logical continuation of moronic recruiters doing blind keyword scanning and hiring managers who don't give a fuck. Then they wonder why they can't hire or retain anyone. It's not your fault they suck shit. This app looks useful when used as intended. At least with this app, they (the company) can't turn it into doing unpaid work on their app that they then keep or using the interview as a dumping ground for problems they themselves are stumped on (Amazon loves doing both of these things). At least not yet.
