I had applied to this company multiple times, and eventually got a call from a recruiter for a suitable role. After a quick discussion about my experience, I was given a HackerRank test to complete within 2 days.

After clearing the OA, I heard back in about 10 days and was scheduled for a CoderPad round.

CoderPad Round (45 mins):
There were two questions, both DP-based.
One was similar to staircase/count ways type problems, and the other involved navigating a 2D grid (from start to destination with constraints).
This round was mainly for screening, and the focus was on approach and correctness.

A few days later, I got confirmation that I cleared this round and was invited for a “Superday” (multiple rounds in a single day). I couldn’t attend the initially scheduled date due to another interview, so I requested the next slot, which was scheduled about 2 weeks later.

Superday Rounds: each with two interviewers

Round 1 (DSA – 1 hour):
Two questions were asked, both LC hard.

First was a grid-based problem involving counting connected components (similar to number of islands, solvable using DFS/BFS).
Second was a string problem similar to minimum window substring, involving hashmap + sliding window.

Both questions required careful handling of edge cases and optimization.

Round 2 (Concurrency + LLD-ish – 1 hour):
This round focused more on core Java concepts rather than pure design.

Questions on concurrency: what it is, how it works, ways to create threads
Coding problem: print numbers from 1 to 100 using two threads
Follow-up: one thread prints even numbers, the other prints odd numbers, and output should still be in sequence

There was also a discussion around how authentication and authorization works in large-scale systems.

Based on feedback from these rounds, I was moved forward the same day for another round.

Round 3 (HLD – 1 hour):
This round started with discussion on my past projects.

Then I was asked to design a URL shortener system.
The focus was mainly on:
Database design
How to generate unique short URLs

Due to time constraints, the discussion around read/write flows was brief.

Next day, I got confirmation that I cleared the technical rounds.

Hiring Manager Round (30 mins):
This was more of a discussion around:
My past experience
Why I’m looking for a change
What I expect from the role

It was a fairly relaxed conversation, along with some questions from my side about the team.

The next day, HR confirmed that I cleared the process and they proceeded with the offer.
The offer process took around 2 weeks, but it didn’t align with my expectations, so I decided not to move forward.

Overall, the process had a strong focus on DSA fundamentals, problem-solving under pressure, and core concepts like concurrency and system design.
