I applied online. The process took 5 weeks. I interviewed at Alcoa (Pittsburgh, PA) in Nov 2016
Interview
Applied online, two phone interviews first with an HR guy then a couple of people from the team. I then visited the technical center where I met with other scientists on the team and presented for 30 minutes about my research. It was a great experience! Everybody was polite and professional.
