First a Codility test from home. Results were not shared. However they invited me on site. 2 Codility tests of half an hour each to start with that were quite easy. First one went well although it produced 20% success because 2 tests (of the ones that Codility runs after the solution submission) failed although all the other passed and the complexity was the required one. I asked the interviewer to discuss them and check the results but he refused. He mentioned that he didn't understand why they failed but didn't care about it. The second test although straightforward I didn't have enough time to compile it and run the default tests. The algorithm was written though. Again I asked him to discuss it but he refused. He didn't even comment on the code I wrote. To sum up, very poor interview process only based on the Codility results which are not evaluated by the interviewer as the score only matters.
