    Network Support Engineer Interview

    Anonymous Interview Candidate in Lowell, MA
    Anonymous Interview Candidate in Lowell, MA
    Application Details

    I applied online. The process took 3 weeksinterviewed at F5 Networks in September 2014.

    Interview Details

    I had applied online for this position and I got a call from the company recruiter the following week asking me details about my background. Once that was done, he emailed me a list of technical questions which I had to answer and email back within 30 minutes. They are pretty straight forward if you know your concepts. The following week, I was asked to come over for an in-person interview with the entire team.

    Every person who interviewed me was very friendly, professional and had little humour as well. I felt extremely comfortably the whole time. The first person had a technical screening worth 75 minutes or so, after which I was interviewed by two people from the team discussing mostly about my background and work experience. After that I had a brief conversation with the vice-president of the company, who was also very friendly. Overall it was an excellent experience. Every one at F5 Networks handled the whole process with great professionalism, unlike few others I had interviewed for before.

    Interview Questions
    • Questions were very detailed. One part was related to networking were quite straight forward if you know your stuff. All the questions pertained to OSI model (L2 to L4), HTTP and SSL. Make sure you know these concepts thoroughly. The other part was all based on Unix and Linux CLI. They were all mostly basic questions and I was able to get through the entire interview process comfortably.   Answer Question
    Negotiation Details
    Very convenient. I was happy with the offer provided to me.

    Enterprise Network Engineer Interview

    Anonymous Interview Candidate in Boulder, CO
    Anonymous Interview Candidate in Boulder, CO
    Application Details

    I applied online. The process took 3+ monthsinterviewed at F5 Networks in April 2014.

    Interview Details

    This was a multi-staged process that took a few months ... first with a phone interview, then a group interview, then about a month later a series of several 1:1 interviews. I had hoped the process was a little faster paced than it was. Overall, it covered broad array of topics in a relatively newer field, DevOps, which essentially merges two realms (Networking and AppDev; L2-L7).

    Interview Questions
    • Not too unexpected, but the more nuanced question surrounded explanations of how the TCP protocol operates in certain conditions.   View Answer
    Negotiation Details
    Was fairly straightforward. Dealt with the HR folks with any questions or negotiations I had and they were willing to see what they could do, if anything.

    Network Support Engineer Interview

    Anonymous Interview Candidate
    Anonymous Interview Candidate
    Application Details

    I applied online. The process took 2 weeksinterviewed at F5 Networks.

    Interview Details

    Phone technical screen by HR. Interview loop consisted of being interviewed by technical, managerial and director personnel. Each was roughly 1 hour in span in a meeting room followed by a follow up with HR.

    Technical interview was the standard sort to prove competency with Unix and Networking.
    Managerial interview involved conflict resolution, work flow, time and issue management
    Director interview involved more intra-workplace conflict resolutions and career discussion.

    Reasons for Declining

    It wasn't a position I was in love with and they understood that. Was very happy to spend time with them and would work there if a new position that fit did arise.

    Network Support Engineer II -- UNIX Interview

    Anonymous Interview Candidate in Seattle, WA
    Anonymous Interview Candidate in Seattle, WA
    Application Details

    I applied online. The process took a weekinterviewed at F5 Networks in January 2013.

    Interview Details

    I was initially contacted by email, to setup a phone interview. The phone interview was standard technical questions. I was contacted later that day to schedule an in-person interview. It was a panel review; an Engineer handled the technical questions, while three Managers were asking other questions. The Managers are always trying to get you to say something negative; be it about yourself, another person, or another company. Don't fall for it.

    Interview Questions
    • I had a Manager repeat over and over that "F5 is not an Information Technology company.", while he was reviewing my resume. I asked why he was repeating himself and he claimed he wasn't repeating himself. (?) After he started reviewing my resume again, he started repeating himself again, "F5 is not an Information Technology company." It was the worst interview. I lost all respect for F5 because of that interview.   Answer Question

    Network Engineer Interview

    Anonymous Interview Candidate in Seattle, WA
    Anonymous Interview Candidate in Seattle, WA
    Application Details

    I applied through an employee referral. The process took 4 daysinterviewed at F5 Networks in October 2011.

    Interview Details

    The interview process consisted of two parts. One part team technical interview and second part high level though process one on one style. Overall I enjoyed the interview sessions. The only pain factor was that they were setup with one day’s notice, this made it kind of difficult to schedule around my previous employer.

    Network Support Engineer II Interview

    Anonymous Interview Candidate in Spokane, WA
    Anonymous Interview Candidate in Spokane, WA
    Application Details

    I applied online. The process took a dayinterviewed at F5 Networks in November 2010.

    Interview Details

    I was impressed with the F5 interview process - the HR person seemed pleasant and friendly. The HR person asked about 10 - 12 very technical questions on the networking side of things and 10 questions on Linux that I did not have much experience with so I could not answer the questions. I took the phone interview because I did not know how deep the Linux knowledge would be reqired (I know enough to be dangerous.) I also was honest on the supplemental questions when I applied online and said that my knowledge of Linus was very limited. Even though I did not pass the Linux portion, some study material was recommended and I can call back and retake the Linux portion.

    My advice it to study the TCP/IP and OSI model like you were back in college. Can't comment on the Linux portion as I was only asked one question but if the questions were anything like the TCP/IP networking questions then I would study Linux the same way. There are bonuses for customer service satisfaction at the end of the year and the salary range seemed approproiate for what I researched (high 60's to low 70's plus bonus.) for this type of position.

    Interview Questions
    • The only TCP/IP questions I missed was to name the 6? flags within the TCP header. I am pretty sure that was the question - you get the general idea.   View Answer
    • What is the TCP/IP handshake process? or something like that...   View Answer
