Engineering Software Research & Development Software Developer interview questions

I was emailed by director of operations and invited to interview. I was so pleased because this position really did match my skills - well, at least it matched those that were posted in the job description. In short, the interview was very aggressive and I wouldn't have applied had they actually posted the correct job description. There was a hostile interviewer that chose to keep putting me on the spot with problems that he had solved and how would I have solved them. I couldn't answer them because of his intimidating attitude and causing my brain to go blank! If only interviewers realized that the interviewee is nervous enough they may think differently about getting the best out of the interviewee. I didn't waste my time at the interview(I'll know not to feel intimidated next time), quite frankly they wasted their time. They were also unprofessional in not escorting me out of their offices. They did not get back to me to say I didn't get the job - something I think employers should do if you actually meet face to face.
