Summary
I interviewed for an SDE 2 role at Kotak Mahindra Bank in Bangalore, completed a Bar Raiser round (DSA, LLD, HLD) and a second DSA round, but was rejected after the second round.
How it went
Status: 2.10 YOE Position: SDE 2 Location: Bangalore
Round 1: Bar Raiser (DSA + LLD + HLD)
- DSA: Minimum Size Subarray Sum (Find minimum length subarray for sum >= target): https://leetcode.com/problems/minimum-size-subarray-sum/
- LLD: Design an E-commerce platform. Heavy discussion on database schemas.
- HLD: Data consistency strategies in distributed systems (Discussed Quorum, Two-Phase Commit / 2PC, and Leader-Replica architectures).
Round 2: DSA
- Question 1: General array/string question.
- Question 2: Segregate prime and non-prime numbers in a Linked List. A variation of Odd Even Linked List but with prime logic: https://leetcode.com/problems/odd-even-linked-list/
Verdict: Rejected in Round 2. I was not familiar with standard Linked List manipulation patterns and fumbled the implementation.
