Interview Process

The interview was conducted by an interviewer from Eastern Europe. I prepared various coding challenges, but the actual question focused on refactoring code for a chatbot. The task involved handling different Slack messages with various action commands, where the message prefixes determined the action type to be executed. After reading the problem for a while, I managed to write the code, but I accidentally deleted the original code and didn’t get a chance to run it. The interviewer reassured me that he understood my approach. Overall, I felt the interview did not go well.

Due to my extensive experience with Python algorithms, I switched to Java for the later part of the interview, as it was closer to a production environment. This change cost me a considerable amount of time.

I initially planned to take a break before interviewing again, but after being contacted by a recruiter about an attractive opportunity, I decided to give it a try. It has been several years since my last interview, and I suspect I may not have performed well in this round.
