KMB | SDE - 2 | Bangalore | July 2024 [Offer]

My Interview Journey at KMB

Round 1 (Bar Raiser) - 1 hr 30 min

This round was conducted by a third party. It was split into three sections:

• DSA (30 min): I was asked two medium-difficulty questions.
• LLD (30 min): I had to design the backend components for an online marketplace, considering features like user authentication, product listing, search, shopping cart, and order management. My approach involved creating classes, an ER diagram, and API designs.
• Tech (30 min): This segment covered design patterns, caching (specifically Redis and CDN), Kafka, distributed system concepts, and sharding.

Round 2 (DSA) - 1 hr

This round was taken by an Engineering Manager from Kotak. I was presented with a problem involving a data stream:

/*Stream s = new Stream();
s.add(2);
s.getFirstUnique(); // 2
s.add(2);
s.getFirstUnique(); // null
s.add(3);
s.getFirstUnique(); // 3
s.add(4);
s.getFirstUnique(); // 3
s.add(3);
s.getFirstUnique(); // 4

I implemented this using an LRU (Least Recently Used) approach.

Round 3 (Hiring Manager) - 1 hr

This final round included a High-Level Design discussion, which was centered around designing a survey system. Additionally, I was asked some standard behavioral questions.

Verdict: I was selected for the role!

My notice period is 3 months.
