    Negative Experience
    Average Interview

    Application

    I applied through an employee referral. The process took 4+ months. I interviewed at F5 Networks (San Jose, CA (US)) in September 2011.

    Interview

    Hiring process took much longer than expected. The recruiting team was efficient but the time before the decision was made by engineering department was extremely long. The process looked totally stucked at some point and I was close on accepting the alternative offer. But overall, I am happy that waited.

    Negotiation

    No room for negotiation was offered, not for the title not for the salary.

    Principal Software Engineer Interview

    Anonymous Employee in Seattle, WA (US)
    Accepted Offer
    Positive Experience
    Difficult Interview

    Application

    I applied online. The process took 4+ weeks. I interviewed at F5 Networks (Seattle, WA (US)) in March 2014.

    Interview

    Very thorough process that involved a phone screen, followed by an on-site interview with ~6 others. The on-site interview started with a small/simple paper exercise on basic programming questions. This appeared to be used to seed one of the interviews. The individual one-on-one sessions were done with talented folks from those fairly new to long term veterans of F5. Each interview was unique, but each seemed more of a collaborative investigation more than simple questions and answers. White board work and general talk through things was encouraged. Overall felt like a solid interview such that when I received the offer, I was sure that I would be a good fit.

    Interview Questions

    • Questions weren't limited to my area of experience and some were more of a collaborative investigation with a subject matter expert. Working through questions about allocating tight structures and then manipulating them were challenging for on-the-spot work, but were actually fun in the end.   Answer Question

    Negotiation

    The whole process of moving to the offer was slowish and methodical as F5 takes hiring seriously in terms of budgeting and job fit. Negotiation was limited to relocation funds.

    Average Interview

    Application

    I applied through an employee referral. The process took 4+ weeks. I interviewed at F5 Networks (Seattle, WA (US)) in June 2015.

    Interview

    After initial phone screen, there was a full day, onsite interview loop. There were five technical interviews which included whiteboard coding problems and lunch with hiring manager. I received an offer approximately one week later. The interview process itself was fine however the coordination of the interview by the recruiting department was not handled well.

    Average Interview

    Application

    I applied online. The process took 3 weeks. I interviewed at F5 Networks (San Jose, CA (US)) in June 2018.

    Interview

    I never had such a bad experience as a candidate. The recruiter from F5 networks scheduled a Technical Phone screening with hiring manager . Received a call from hiring manager after waiting for 5-10min that interview needs to be rescheduled due to some unexpected event. Such things do happen in life.

    Phone interview got rescheduled in following week. Just few minutes before the interview, I received an email from recruiter that interview needs to be rescheduled due to some reason.

    I wrote a reminder email after few days. Got a voicemail from recruiter that my profile is not fit for the job position.

    I strongly feel that F5 Network does not respects candidate’s time and effort.

    Principal Software Engineer Interview

    Anonymous Interview Candidate in New York, NY (US)
    No Offer
    Negative Experience
    Average Interview

    Application

    The process took 4+ weeks. I interviewed at F5 Networks (New York, NY (US)).

    Interview

    Recruiter and VP were a pleasure to talk with. Very responsive and great to discuss the opportunity with. Final technical interview was with Chief Architect...

    Could tell from the get go that he did not prepare for the interview. Position was for cloud technologies but no questions related to position were asked. Continually interrupted and asked completely different questions as I was providing a solution to the original question. Once I was able to provide the solution, he asked why made an assumption. I had to explain that we agreed on these assumptions in the beginning... Could tell that I did not fit the "cultural" person he wanted (clone like him).

    Overall, the recruiter and VP were great and represented the company very well. Unfortunately, would not accept a position where such an unprofessional individual would have that much input on the team. Fortunately, they didn't extend one.
