That interviewer was not cut out to be an interviewer. That's right on the mark of unprofessional and most likely challenging individual to work with.The interviewer even suggesting that I simply wasnt cut out to be a mechanical design engineer as a result.
In general and depending on industry and exposure it takes about five years to develop a vertical skill set in most ********** and technologies as an engineer as well as designer.
