Cerium Systems Project Engineer interview questions

The Interviews process is very simple and sorted but difficult to crack. Following are the steps on how the process goes: 1. General Aptitude Test with negative marking 2. Technical Round (Written) 3. Technical Interviews 4. HR Discussions

1st stage is quantitative aptitude+logical reasoning maths qs + technical test covering digital electronics, microprocessor, c/c++, op amp waveform etc....once passed, 2nd stage is technical intv on digital electronics,verilog,c/c++ and 3rd stage is hr interview but I was skipped on this stage
