Typical interview process starting with introduction about yourself, strengths and weaknesses, testing technical knowledge and motivation to see if you fit. Usually the interviewing process starts by making the interviewee comfortable and depending on a few factors such as how much they need to fill this position; how many potentials they have; how much they see a fit based on initial screening; and chemistry before they decide whether to use the short or long process. Short will jump straight into technical before asking perfunctionary ones while longer will take the entries process and then again with another senior staff. I got the short one as i had very similar background and when I moved to the second phase the process started again with another senior staff albeit on an accelerated interviewing pace. Good luck
