Revolut Senior Software Engineer interview questions

Just some standard Coding Challenges mostly focusing on speed and slightly on correctness too. If you work for a while to prepare your coding speed then you will find it easy mostly. However, they do ask you regarding Multithreading so you gotta have those concepts very clear beforehand.

Applied to an offer in LinkedIn. Contacted by them, and scheduled the first interview. The first interview was just a 10 minutes talk with one interviewer. 5 minutes where she told me about Revolut and how they work, 3 minutes talking about my experience, and the rest for 2 plain questions about if I knew the complecity of a hashmap, and the meaning of transactionality. The questions were plainly read by her and there was no discussion at all, quite cold and. Rejected after it because of another more fitting candidate.
