I had 2 phone screening: First one about MOSFETS, TRANSISTORS, and the asked me if I Know c/c++ programming and I replied no. So they said they will get back to me if needed. So the HR said there is a second round of interview in C/C++ alone. I prepared for 3 days and th interview was set. They interviewer knows I am new to programming and then he asked too deep questions in OOPS concepts ffor about 40 mins .
