I did a full complex coding challenge and submitted it, 2 weeks later I got an email asking me if I had done it. Passed the exam but was not hired, 5 months later I was contacted again, with a new process, most of my feedback clashed with my previous challenge, they had no clue how to interview or what they were looking for, for a front end position I was asked for an extremely simple exercise and still got a bad feedback on questions.
