This was one of the worst interviews I have ever experienced. The interviewer did not have the knowledge to even understand basic code. They will give you a hard-level LeetCode question, which is difficult to complete within 30 minutes. In that 30 minutes, they want you to dry-run code, then write executable code with proper variable names, SRP for every method, and a lot more expectations. This is only possible if you remember the complete problem code. So, I would suggest not wasting your time here, because they think they are hiring diamonds, where the people who are conducting the interviews are useless stones.
