I applied through university. The process took 1 day. I interviewed at Martin Marietta Materials (Fort Collins, CO) in Apr 2020
Interview
was for CSU career fair the interview was pretty fast and east and I wasn't what they were looking for but overall looks like a good company and the internship program seemed like it would teach you a lot
My experience was amazing, two round of interviews and everyone I spoke to was really friendly. The interview was more like a conversation rather than an interview. The process was rather quick.
