Interview preparation tips for other job seekers - Be confident about your concepts. Sometimes they will pose questions where there is a missing information and you need to point it out. Smile in between and remember that you should answer the questions in a simplistic manner so that even a non-tech background person can understand your answers. This is very underrated and very much appreciated. Using fancy technical jargons is not appreciated.
