Time waste.

• 1 HR Introduction call
• 1 Manager Call (Casual Discussion on role)
• 3 Technical Interviews (DSA, OS, Multi-threading + System Design and Puzzles + DSA)

It took the whole day for the interview. The first interviewer was flat out rude and didn't even bother to exchange pleasantries.

Disrespectful offer, and they didn't even acknowledge the first conversation. I had already made my expectations clear; I shouldn't have wasted my time with such low offers, especially those even below my current compensation. That's not what someone expects after clearing so many rounds of interviews.

Simple producer-consumer multi-threading problem.

Tree-based questions, general C++ concepts, puzzles.

Design a Gmail system.

OS: Mostly concurrency part.
