Had to go through a 3 stage interview process for an intern position. first round : Was more on what I knew about digital design, few questions on adder/subtractor were thrown. Couple of questions on latches and flops. Detailed operation of transistor, with curves and v/i equations. second round: was more on layout , was asked to draw layout of a mosfet, I was very comfortable here thanks to the interviewer, it was more like a discussion. fairly easy. third round: I was asked on logical reason (kind of strange), then was asked to write a algorithm to draw a rectangle , then using this logic I was asked to draw layouts with varied shapes. This was fun, the interviewer more looking towards my approach than the correctness. Finally , had an interview with HR , where I was told more on the internship details, policies etc.

two rounds of interview. one based on digital design concepts and other one based on system verilog and questions on projects mentioned in the resume. one puzzle question was asked which was easy enough to solve
