I had a phone interview followed by the technical interview on the phone. The phone interview was just characteristic questions. Nothing unexpected at all. The technical interview however required knowing most of C++ functions. I had mentioned I have not used C++ in few years and was told its okay. The questions were like what does X function do? I was also given a shot code and asked for the output. Matlab and Math questions were easy. stuff like whats the relation between the acceleration and velocity. Find inverse of this Matrix? How can you check to make sure it is correct? ( A. A^(-1)= I ) As of the control theory that I had selected: I reviews the notes from my junior level classes and I was able to answer them all. ex: why poles on the left half axis on the complex s plane lead to system stability But I screwed on the C++ well enough to not want to even waste the time of the interviewer any more. Overall I believe if I was to take this technical test right out of college with my BSME I would do great.. but not having done any programming during my master's I needed to study a lot more.
