### Application Process
A friend forwarded my resume to HR, and HR reached out a few days later to schedule a 90-minute Bar Raiser round.

### Interview Experience
The interview was outsourced to BarRaiser (the interviewer wasn't a Kotak employee). 

There were 3 sections:

**Section 1: DSA**
I was asked 3 questions. Working code was expected for all three along with custom test cases:
1. [Roman to Integer](https://leetcode.com/problems/roman-to-integer/description/)
2. [Find the Index of the First Occurrence in a String](https://leetcode.com/problems/find-the-index-of-the-first-occurrence-in-a-string/description/)
3. An extension of [Subarray Sum Equals K](https://leetcode.com/problems/subarray-sum-equals-k/description/): Return all subarrays whose sum is a power of 2.

**Section 2: LLD**
Design an **Event Management System**. 
Expected topics: API design, database schema and indexes, class diagrams with pseudocode, and relevant design patterns. It was expected to focus on locks and consistency also.

**Section 3: Distributed Systems / HLD**
General High-Level Design concepts:
* 2-Phase Commit (2PC)
* Eventual Consistency vs. Strong Consistency (CAP Theorem)
* Optimistic vs. Pessimistic locking

### Takeaways
Overall, the questions were on the easier side, but cramming 3 DSA problems, LLD, and HLD into a single 90-minute slot felt like way too much. Managing time was extremely difficult, and the interviewer wasn't very interactive.

**Verdict:** On hold. HR informed me that they have already identified enough candidates for the role.
