General impression: I liked the interview with HR, a very nice guy, despite my English with him, the conversation was easy and interesting. Today there was a technical interview, I really enjoyed talking with Richard, you really want to work in a team of such people. Most likely, I did not pass, I was bad at OOP, and when I myself realized this, I began to worry a lot. In the end, he cheered me up, in short, I really liked the interview experience with this company, I rarely came across such pleasant interviewers. Regardless, it was an awesome experience. Summary: The tasks are not difficult, but you need to  repeat and recall the theory well and OOP
