I worked at CDM full-time (Less than a year)
GREAT people, ALOT of experience- more than i would have gotten in that role elsewhere
Things take reallly reallllyyyy long to happen (promotions/moving to a new team) Upper management doesn't care all that much
I applied through an employee referral. The process took 2 weeks. I interviewed at CDM (New York, NY) in May 2017.
HR called me for a phone screen then set me up with a 45 min interview with 3 VP/Copy Supervisors and gave me a tour of the office. It was a very informal interview
