They contacted me themselves through a talent website. After a brief (barely informative interview) they went forward with a set of 2 "take-at-home" style exercises on said website's platform. I happened to be familiar with both of those, so not only did I give solutions that passed the tests, I had time to implement my own (extensive) unit tests. The tests were about 90min long, so together with some practicing to get familiarity on the platform beforehand, I spent 3-4 hours. Bigest waste of time ever. Not only did they respond with a generic "sorry there was no fit" answer, but they never bothered answering my request for more feedback. This is not how technical interviews work guys....
