Was initially contacted by a Juniper recruiter. Spent 30+ minutes with him in a phone screen. Was set up a few days later with a phone interview with hiring manager which lasted for over a hour. The following week, was set up with an in-person interview and met with 2 managers and a lead. Each interviewed me individually, and the entire in-person process lasted over 3 hours. Finally, was set up with another phone interview with another manager 2 days later, which lasted over an hour.
