Very straightforward interview process rather than convoluted. I've heard some companies doing over 5+interviews before an offer but this was less than that whilst ensuring they got to know you.

I applied online. I interviewed at Juniper Networks (Sunnyvale, CA) in May 2023
Basic process. Seems the interview process would take 2-3 round of conversation. The HR did a phone screen and then scheduled an interview with the hiring manager. I did the interview and then received a msg from HR they wouldn’t move fwd with the process.

The recruiter completed the first stage of my interview following which I managed to get through the next round. The Manager who interviewed me was wonderful and did say the recruiter will contact me regarding what the next part of the process should involve and received verbal confirmation that I am being selected for the next round of interviews. Yet, 2 weeks later I received an email advising the position has been filled. This is highly unprofessional.
