20-25 multiple-choice questions covering topics like DSA, OS, and code snippets.
One coding question (Medium level):based on Bit manipulation .
Round 2 (Technical Interview Round 1):
Medium-level DSA questions: Majority Elements, Merge two sorted Linked Lists into one.
Operating System Questions: Dynamic memory allocation (Hard level), Internal implementation approach (e.g., malloc in C).
while we do dynamic memory allocation we give size to malloc in C language but while freeing that memory it doesn't take size.So how do you think internal working of that?Tell me how can you implement that ?
Operating System Implementation: Multithreading, Deadlock.
