Tinkoff Credit Systems Bank Data Analyst interview questions

there are 3 steps: test, mathematical tasks and analytical tasks. Test was about 50 minutes, mathematical tasks was about 1 hour and analytical tasks was about 1 hour. Sometimes interviewers helped you to solve tasks.

usual pre screening with hr. then had tech interview, which consisted of tech questions + live coding (sql). Did not expect live coding, could not test my code, had to write it without running it first. Could have done better, if I knew I needed to live code
