I applied online and got a team interview the next week. They looked very nice and we had a wonderful experience. I was given a second-round interview the next day. The second-round interview was also very good. They basically asked me my Stata skills and they extremely cared about your passion for this job. People seemed very friendly and it was one of my best interview experiences talking to them. However, I didn't hear them back in a month until the HR called and asked for my salary expectation. They could only offer 55k, and I really couldn't accept it. So I didn't hear back from the HR.
