Technical Coding
The interview process at Juniper was pretty much what I expected for a C programming job. I figured there'd be C programming questions, and there were. A lot of them were familiar, either ones I'd encountered before or used myself during interviews, so nothing really caught me off guard. I actually enjoyed the more open-ended questions, as they gave me a chance to engage with the interviewer and really showcase my abilities.

Technical Behavioral
The manager called me 15 minutes late for the interview and seemed to have already decided against me. They asked technical questions that weren't even related to the job description, and honestly, the manager didn't seem to know what they were looking for. It wasn't a good fit, which is fine. What really made this a bad experience though, was that the recruiter never replied to my emails after the interview. That's super unprofessional. A simple "thanks but no thanks" would have been polite and showed they were doing their job!

Had a phone interview that lasted about 30 minutes. About a week later, I went in for an onsite interview. They made a decision a couple days after that, and then the background check started. The background check took about a week to complete.
