College: Not Specified

Interview Date: 2022

Interview Type: Off-Campus

Result: Rejected

Difficulty: Challenging

Rounds: 3 main rounds (4 parts in total)

Topics Asked: DSA (Graph-based), Multithreading, Race Conditions, Operating Systems, Data Structures, CS Fundamentals

Experience:

This off-campus SDE experience involved four parts, each an elimination round.

Round 1: Coding Test (90 minutes, Talescale platform)
This round had 3 DSA-based (Graph-based) questions. The common problem description was a maze with N cells, each with at most one exit.

• Nearest meeting cell of two given nodes x1 and x2.
• Find the node number of the maximum weight node (sum of all nodes pointing to it).
• Find the Length of the largest cycle.

The candidate explained approaches for these problems and was selected for the next round.

Round 2: Hackathon Round (2 parts)
This round was described as challenging.

Part A (Coding Test): A question similar to "Tree of Space" was given. The candidate solved it after about 1.5 hours with some wrong submissions.

Part B (One Day Hackathon type Discussion): The task was to write the Part A code to handle multithreading and avoid race conditions. The round involved describing the Part A solution, then applying multithreading. The discussion covered new concepts of operating systems.

Round 3: Technical Interview Round
The interviewer joined late but was good. The round focused on CS fundamentals like OOP, CN, DBMS, and DSA. The candidate was rejected in this round.
