Round 1: Problem Solving

• Question: File read/write operations using an offset. Follow-up was based on multithreading on this.

Round 2: Concurrent Data Structure Design

• Question: Design a data structure that supports search, insert, and delete operations with strict concurrency constraints.
• Multiple search operations can work concurrently.
• Only one insert at a time (searches are still allowed).
• Only one delete at a time, which strictly stops both inserts and searches.
• Hint: Requires deep knowledge of Read-Write locks and thread synchronization.

Verdict: Rejected. I struggled with the concurrency implementation in the second question and couldn't fully solve it.
