I applied through an employee referral. The process took 2 weeks. I interviewed at DuPont in Mar 2019
Interview
The phone interview was with the lead scientist from the department I applied for. They first asked me some general questions such as why am I interested in the job and the company and my overall research / experiences, then they went to technical questions. Since the team works on computer vision and machine learning stuff, they asked a lot of detailed questions on that, but generally the questions are easy.
