Interview Round 3(45 mins | DSA | Subjects):

Interviewer asked me to pick a project and briefly explain. He cross-questioned about the assumptions made and about all the features and calculations made.
He asked me about Exceptions(JAVA) with examples. He gave me a real-life example and asked me about the exceptions which may arise.
He asked me about threading(OS) and how can it create a problem and how to tackle the problem.
He asked me about MRU(most recently used page algorithm: OS) and about its real-life application.
Difference between abstract class and interface and examples for it and why do we use it.

He then asked whether I had written the complete codes for previous rounds and then gave me two basic coding questions. I was asked only for the logic and not the code (for both)
