Was contacted to schedule an interview via e-mail shortly after I submitted my job application. It was subsequently rescheduled twice (I guess it happens). I was originally supposed to be interviewing with 3 people, but ended up talking to only one of them. The interview took about half an hour, it was a pleasant conversation. The interviewer made me feel at ease. He asked me to walk him through my resume (standart questions), then he asked a few statistics, data cleaning and machine learning questions to test my knowledge of the subject and to evaluate my thought process. He seemed to be satisfied with my responses. At the end I walked out feeling pretty good overall. Alas I did not get the offer. Not a big deal, part of the job searching game :) The only negative was that I did not get a rejection e-mail, nor any response after I had followed up with them. I figured after additional 4+ weeks of waiting, no response means 'no offer' which was a bit frustrating, but again it is not an uncommon way to turn down an applicant.
