I did not enjoy the interview process with American Tower, mostly because it took SO long (over 3 months - see below) and they provided no feedback throughout the process. +May 18 applied for job +June 1 phone screen with recruiter +June 5 phone screen with hiring manager +June 22 in person interview +July 7 second round in person interview +August 28 follow up call from a different recruiter - I didn't even bother connecting with her because I had already accepted another job. Overall a very irritating process.
