Technical Coding Behavioral
It was an on-campus opportunity. The first part was an online assessment (OA) which mainly had fundamental questions covering C++, Operating Systems (OS), Computer Networks (CN), Linux, and aptitude. After that, there was an interview which included basic Data Structures and Algorithms (DSA) questions and tested my understanding of C++ concepts like pointers, Object-Oriented Programming (OOPs), and memory management. Since my project was related to OS, I was asked several questions about it.

Technical Coding System Design Behavioral
Had an online assessment with 30 MCQs covering CNS, OS, JAVA, OOP, and C++. Then, there were 3 rounds: the first was technical focusing on DSA (easy to medium, like LeetCode) and CS fundamentals, with a strong emphasis on Operating Systems and deep dives into OOP and computer networks. The second round was system design, and the third was a typical HR round.

Technical Coding
It was a horrible experience. The interview was set in ITC Windsor hotel in Bangalore. It began with a written test that mostly consisted of MCQs about syntax and program output. They didn't have proper arrangements for the face-to-face interviews. They took me to a smoking area where a few canopies were set up. Other hotel guests were walking around, which created a pathetic environment. The story doesn't end there; they also didn't have enough panel members. The interviewer was simultaneously conducting multiple interviews. He gave me one question and then left for another. By the time I finished, he had almost forgotten what we had discussed earlier. It seemed to me that the whole group was just interested in meeting their interview numbers and were least interested in the candidate's interest. The interview round lasted for 3 hours in total, and even after providing the best possible optimized solutions, I received average feedback. I later found out that the same feedback was given to everyone present.

- Can you write code to print a star formation?
- Determine if two given strings are anagrams of each other.
