The interview process was just one big waste of time. Applied for a front-end position in Helsinki, went to 5 in-person interviews, 3 technical ones and two soft skills and work practices (plus the algorithmic task I was supposed to complete). It took two weeks, but only because I told them I had other offers. After this amount of I was invited to their office, waited there for about half an hour, only to be invited into the room to be given rejection. After I asked why, the HR person started mincing words, she looked physically uncomfortable, said that this is 'classified information'. Them she proceeded asking me for the feedback and as I started, she was interrupting me repeatedly, which was extremely rude. I at some point asked 'Do you want to listen or not?'. After repeatedly asking for the feedback from the interview, I received some vague 'you refused to answer some questions', 'you should know more about REST API design', etc. Later they suggested me to apply after a couple of years again or to a more 'junior' position. Very disrespectful.
