How was your test and interview experience for an M.Tech at IIT Gandhinagar?

I completed my B.Tech ECE. Due to Covid-19, I got a direct interview call from IIT Gandhinagar for M.Tech ECE. I got interviewed on Google Meet.

Out of the four choices given to me, I opted for microelectronics and VLSI as my first preference. 20 minutes prior to the interview, I received a call from the technical supervisor asking me to be prepared. There were 3 panelists for my interview and all of them belonged to the Electrical Engineering Department of IIT Gandhinagar.

The interview started with a basic introduction and I was asked for my favorite subjects. After this, I was asked questions to assess my knowledge of the field. I am listing down the questions which the panel asked me-

• What is the propagation delay in logic ckt, why does delay occur?
• Explain NOR and NAND gate.
• Explain BW of an amplifier.
• Explain BW of the single pole system.
• What are the conditions for which the gain BW product is constant?
• Differentiate ideal and real op amp.
• Draw a T C curve of both.
• O/p for open loop op amp.
• What is CMRR, and what is common mode gain?
• What is the BW of (real) op amps?
• Does Amplification violate energy conservation law?

The IIT Gandhinagar staff is quite helpful and supportive. I received 3 calls every 15 minutes to alert me before the interview. My interview went well and I got selected for the M.Tech program.
