It depends only on you how you represent yourself, in the interview. I believe that your pride should never fall down because of some sort of interview. Moreover, I would never do that because you never know if you will get this job or not, so it doesn’t make any sense, pretending to be someone else. You may be yourself and after the interview, you could just thank the company for the chance they offered you. You may check on the internet some good templates for a thank you
email. This will help to improve your image on a better side.
