Interview Type: On-Campus

Result: Rejected

Difficulty: Medium to Hard

Rounds: 2 technical rounds

Topics Asked: Data Structures, Algorithms, Object-Oriented Programming (C++/C), Computer Architecture, Operating Systems, DBMS, Networking Basics, System Design

Experience:

This experience is from Chinmay Krishna, a final year undergraduate student of Electrical Engineering at IIT-Kharagpur. He shared his test and interview experience with Plutus Research. [cite: 9 in previous turn]

The interview process for Plutus Research involved two technical rounds. For startup-based companies like Plutus Research, strong knowledge in Computer Architecture and Operating Systems is highly valued. Additionally, a good understanding of DBMS and Network Basics is beneficial, but Computer Architecture and Operating Systems are considered most important. [cite: 9 in previous turn]

Round 1: This round focused on writing functions and utilizing various data structures to achieve specific functionalities. The interviewer presented "design-type" questions, such as efficiently storing a stream of numbers and then retrieving the top 10, last 10, greatest 10, or minimum 10 numbers. After about 40 minutes of discussion on the approach and data structures, the candidate was asked to code the explained functions. [cite: 9 in previous turn]

Specific questions or topics mentioned that could be asked include the "Diamond Problem" (related to multiple inheritance in C++) and "Sparse Matrix Multiplication". [cite: 9 in previous turn]

Round 2: Details for the second round were less explicitly broken down in the provided snippets, but the overall discussion indicated a continued focus on core computer science concepts. The candidate mentioned that a lack of practice in "soft maths" or "p problems" was a contributing factor to his rejection. [cite: 9 in previous turn]

Overall, the experience was challenging, requiring a solid grasp of theoretical concepts and practical coding skills. [cite: 9 in previous turn]
