had 30 mins interview with Project Lead/manager. The discussion went smoothly and the interviewer was a really nice guy and asked python related questions. At last, he said he is going to share a coding test that does not have any deadline. coding test was simple which I completed in 2 days and sent back. The next day I got feedback stating they won't proceed further as my solution does not match their standards. Some of the comments were really disappointing and insulting for e.g. They said: "candidate did not use unittest to test and it shows he does not have knowledge of testing framework". I had used pytest to test the code and used assert to validate the tests. How can you judge me that I don't have knowledge of testing modules just because i did not use 'unittest' library? pytest is equally an acceptable framework which is being used in industry. I think they need to educate their panel who verifies the solutions. moreover, they are looking for a super expert python developer who can work as a tester for them.
