I didn't have a good interview experience.

Throughout the coding interview, I actively sought clarification, asked questions, and maintained open communication with the interviewer. However, I found the interviewer to be very passive, offering minimal comments and guidance.

I completed the coding task in 35 minutes. Despite completing a couple of follow-up questions about potential improvements and runtime analysis, I received little feedback. When I inquired about my performance at the end, I was told that I had covered all the corner cases.

The next day, I received a rejection email from the recruiter. Upon requesting feedback, I was informed that they were unable to provide it.
