    Average Interview

    Application

    I applied online. The process took 4 weeks. I interviewed at Juniper Networks (Sunnyvale, CA) in October 2016.

    Interview

    Found the role on LinkedIn. Standard online application process. Recruiter reached out to me within a few days of applying. First call with Juniper recruiter was smooth. She asked the standard job qualification questions. I was asked to describe my work experience and background. The recruiter was very upbeat and a pleasure to speak with. Shortly after the initial call I received an email asking for my availability to speak with the hiring manager. That call went smoothly. I was then invited to come into the office to meet with the hiring manager and two people from the team. Within a few weeks Juniper had conducted reference checks and an offer was made.

    Senior Big Data Engineer Interview

    Anonymous Interview Candidate in Sunnyvale, CA
    Declined Offer
    Neutral Experience
    Easy Interview

    Application

    I applied through an employee referral. The process took a week. I interviewed at Juniper Networks (Sunnyvale, CA).

    Interview

    The process was pretty much quick starting with a phone screen of 30 mins and then followed by 3 hour on site.

    The on-site is always restricted to 3 hours at Juniper unlike other companies which makes it a good experience. The on-site interview was more of a discussion involving one round of coding with the Manager.

    The technical rounds are not at all complex and give a good idea about the role. Very important to have a good idea bout the role before you go in for the interview.
