Mi9 Retail Software Developer interview questions

awful interview. They send you 2 tests. one is logic test where you have to do math quickly. secondly is the worst test. it's suppose to be a normal c/c++ test but the whole test is about some weird DB language that I never heard about. The only normal C++ question is at the end and doesn't make sense at all. the test cases don't work and the question is not clear at all. The test didn't make sense at all. I just quit the test in the middle.

Interview process was simple and there were 3 rounds. First round was simple and like know each other kind of thing, second was test with team lead directly and third was HR round where company person will explain about company procedure and further steps.
