Deutsche Bank interview questions

The interview was not very difficult; there were questions about experience, questions about knowledge of programming languages and libraries. There were 3 problems, 2 of them can be solved using a straight forward approach, the third is formulated in such a way that you don’t immediately see the solution, but it can also be solved simply (remember the greedy approach). Disadvantages: I did not receive any answers from HR after the interview, even after a follow-up email.
