Imubit Backend Developer (Python) interview questions

I would say it was the first, pre-intervening meeting. nothing special or to tech. General company overview and asked about my project experience. Then there was a live coding session. The problem wasn't too difficult (one of the 1000 typical they asked in interviews), my algorithm didn't pass the test the first time, but in the end, it worked as expected. The next day, they answered that I didn't pass (didn't answer to all of the questions) but there weren't many of them, just 2. So just don't rly like and understand the kind of interview, where the interviewer doesn't give any comment or feedback during the process but in the end as result all is bad
