The complete process consists of two parts. Written test followed by personal interview.
Written test: There were question based on digital electronics, digital vlsi design, analog vlsi design, physical design fundamentals, static timing analysis, aptitude and CMOS fundamentals
Personal interview consists of three rounds:
first interview is by mid senior level employee who focused mostly on resume and VLSI technical questions. Questions on CMOS inverter, Antenna effects, PNR flow, Shell scripts, STA fundamentals etc.
Second technical interview by director level employee. Mostly focused on short channel effects and fundamentals. He checked if the person is able to solve problems with few hints or not.
Last interview was with HR who is also a director. Aptitude problems, Problems on decision making with given situations and circumstances.
Overall process was nice. One day written test of 2 hrs. After a week interview was held which took nearly 2-3 hrs. Nice process.
