The format appeared to be the typical behavior-based questions... "Tell me about a time that you..." Yet the interviewing skill of each of the interviewers, and their interest in the task at hand and their interest in me, varied widely and many did not follow the format (which is certainly fine, as long as it was a meaningful interview and produced the desired results, i.e., good data were collected to form a proper decision). I feel that I interviewed very well - I have interviewed since, with similar companies and roles, and received two job offers (for larger jobs, actually) - and I know that I am more than qualified for the position. But I never heard back from anybody. I circled back to the recruiter and reached out to a handful of the interviewers that said to contact them if I had more questions. I was polite and positive in my queries. But nobody got back to me. This is a very connected community that we work in, and my experience does not seem to be a rare occurrence with Gilead Sciences; in fact, I have heard similar experiences from many people that have interviewed with this company, and it seems to be a common theme.
