3 round interview process. First with HR representative. Second with 3 engineers on the R&D team. Third with 2 scientists on R&D team. All the interviewers were extremely welcoming and asked some standard behavioral questions along with technical questions. I really enjoyed speaking with everyone and thought I had a good chance and was even told that the team really liked me and that things were looking good. However, right before scheduling my fourth interview with the new R&D Director I was told someone else got the job. It was definitely disappointing especially after hearing such positive feedback and really liking the people and company.
