I applied through a recruiter. The process took 2 weeks. I interviewed at Alcoa in Nov 2013
Interview
I was interviewed at a career fair and the recruiters were very approachable. Within minutes I was set up for an interview. The interview was short and it was less of a structured interview and more of just a conversation of what my goals were and why I was interested in the company.
Phone screening, in person interview, very laid back and low pressure. Interviewer was very respectful and nice and gave me time to think through each question. Overall positive experience and would reccomend to a friend.
Stay clear or continue to interview if you receive an offer from them. My internship offer was rescinded late into the internship recruiting period leaving me with no offer for that summer.
I applied online. The process took 2 months. I interviewed at Alcoa (Cleveland, OH) in Jan 2019
Interview
Smooth - started online, followed by two phone interviews and final in person interview. In person part of the interview was rather disorganized and didn't provide transportation (in the winter, with lots of snow) which was strange.
