One written round.

Two rounds of interviews.

The written round had coding (C, C++, Java) and technical (digital design-based) questions. The interview rounds were technical, mostly from basic device physics. Some questions were about PhD work. Some were about personal interests and hobbies.

1. Introduce yourself.

2. Explain PhD work (didn’t allow to use slides and had to explain orally).

3. MOS CV characteristics for LF, HF, different temperature, substrate bias, replacing n+ poly gate with p+ poly, and when source drain terminals are added.

4. Short channel effects: What is DIBL, how to quantify it, and how to reduce it.

5. What is GIDL, what is the mechanism, and how to reduce it (thicker oxide and wide bandgap drain).

6. A tank with two pipes A and B. A can fill it in 8 hours. B can empty it in 16 hours. When both are turned on, how long will it take to fill?
