After having a phone call with an HR recruiter I was sent 2 tests. One of them was IQ test which I don't think is ethical and the other was C++ test. I got strong points from all. I was told that they'll return to me after 1 week of completing the tests. Instead they returned in 3 weeks after I requested respond with a generic rejection letter like my experience isn't enough or smth. Why waste my time in the first place if experience wasn't enough. They don't value applicants' time. Not gonna try again.
