HR first asked about my availability for a phone interview, and I got back to them the same day. I didn't hear back for about a week. Then, they asked again for my availability for the next day, late in the evening around 6 PM. I replied right away and also offered some times the following week just in case. After that, I still haven't heard back and was eventually rejected without even having an interview. I did accept another offer during this time, so it's fine, but the whole process seemed unorganized and had poor communication.

Technical Coding
So the first round was an online test. It had MCQs covering core subjects like OS, DBMS, COA, and CN. Then there was an aptitude section with 30 quantitative questions. After that, it was a DSA section with three problems: LCA in a Binary Tree, Partitioning DP, and String Matching (Rabin Karp or LPS). Round 2 was another coding round, but this time we had to do it on blank paper. They asked for two questions: one was Merge Sort, and the other was swapping the first and last bit of a 32-bit integer, making sure all other bits remained the same.
Confirmed questions2 questions
- Provide the code for Merge Sort.
- How would you swap the first and last bits of a 32-bit integer, ensuring all other bits remain the same?

Technical Coding Other
We had 4 rounds total. The first was a basic coding round covering arrays, linked lists, and bit manipulation, plus some puzzles and OS questions. Round two was more intense with deep dives into bit manipulation, probability, puzzles, OS, and coding. Then came a managerial round with fundamental and academic questions. The final round was with HR.
Confirmed questions2 questions
- Can you solve bit manipulation problems, like setting specific bits or values in hex, ranging from simple to complex?
- How would you approach searching in an infinite sorted array?
