Tech@Kotak Interview Experience [Rejected]
Summary
I recently had a screening round for Kotak that included a coding problem and system design questions. Unfortunately, I was rejected as my LLD skills were not up to par, and I was quite rusty after a long break from interviewing.
Full Experience
I recently had the opportunity to appear for a screening round with Kotak, organized by a bar raiser. The interview lasted 1 hour and 30 minutes and consisted of three main parts: a coding problem, a system design problem, and a discussion on high-level design concepts. I realized I hadn't brushed up on Low-Level Design (LLD) in a long time, and my performance reflected that. This was also my first interview in about a year, so I was a bit rusty.

Preparation Tips
I hadn't brushed up on Low-Level Design (LLD) for a long time, which negatively impacted my performance. I was also quite rusty, as I hadn't given an interview in about a year.
