It was good. Round 1 was a test containing 3 sections: aptitude, C, and electronics (digital/communication). I took the digital one.

Then there were two technical rounds and an HR round.

Basic questions asked were related to:

• Divide by 2 circuit
• 4-bit comparator
• In assembly language, how to check whether a number is even or odd (check the last bit)
• Fourier transform
• Setup and hold time and its violation (metastable)
• D flip-flop explanation
• Noise margin
• Multiplexers

Make sure you know VLSI, Verilog (some were asked a lot), like synchronous reset vs. asynchronous, basic coding in Verilog, etc., microprocessors/microcontrollers, signals and systems, and logic design.

This was my first interview and it went well, but I wasn't selected because only a few were chosen. All the best!
