I applied through college or university. The process took 6 months. I interviewed at Burns & McDonnell in Feb 2015
Interview
Two interviews:
October: In-person 30 minute interview on campus following our career fair - this was fairly general and the interviewer was not part of the group that I wanted to intern with.
February: a 30+ minute phone interview with the CDB office manager and my internship mentor that was specific for the location and type of internship that I wanted
Interview questions [1]
Question 1
What sets you apart from other applicants? - and they really wanted to know, it wasn't just a question on their list.
