Applied online, received a phone call for 1st round of interview. I think they were looking for a person with a little more experience in C programming given I did not receive any feedback.

I went through one initial phone screening with a recruiter and then I interviewed with an engineer. The interview with the engineer started off great - he asked me about my resume and we ran through the projects I had worked on. Then he started asking me technical questions - he started off with software. I flew through some definitions such as what is a "binary search" and "the difference between a microcontroller and a microprocessor". Then he started asking me more hardware related questions. These I was not as prepared for, and I probably should've known the answers ("What is the laplace transform?" "what are the three parts of a mosfet"?). I legitimately could not remember the definitions to some of these concepts, so I began replying with "I don't know" - because I wanted to maintain my honesty. This interviewer was not kind with me. After a few "I don't knows" he lashed out at me, telling me that that is the worst thing to say to an interviewer (I agree, but was I supposed to make something up?). He mocked me and said, "Well I'm sure with your GPA, you are getting lots of offers aren't you?" He went on to advise me to stop looking for jobs and to go to grad school. When I said I didn't have the money, he told me to fib and tell my university that I wanted to get my PhD so that I could get free tuition then quit after I had my masters. Needless to say, I was very unimpressed with my communication with this engineer. I avoid applying to this company at all costs now. I still get upset thinking about the way this interviewer treated me. I'd also like to say that as you can see from my interview questions, this guy was all over the place. He didn't really focus on one area of background - rather, he quizzed me on every fundamental thing I have learned at school and lashed out when I couldn't remember a few.
