I was a referral. I completed an initial interview over the phone with a recruiter. I then received a call letting me know I would be invited for a second interview over the phone with the hiring manager. After speaking with the hiring manager, I was again notified by the recruiter via phone that I would need to come in for an in person interview which we set up while on the phone. The in person interview lasted approximately 2.5 hours. I interviewed with an existing account manager, the hiring manager, and two team leads. Both the account manager interview and the team lead interview were more like shadowing and seemed geared and determining personality fit.
