    Difficult Interview

    Application

    I applied through a recruiter – interviewed at F5 Networks.

    Interview

    Deeply Technical and a lot of customer support questions on how to deal with tough customers. Lots of Linux questions so you must know your Linux fundamentals as well as knowing the OSI model thoroughly and how to set up a basic network and how to troubleshoot it.

    Application

    I applied online. The process took 6 weeksinterviewed at F5 Networks in December 2014.

    Interview

    Applied online, took a long time to get the phone screen scheduled because the HR personel was on vacation. Finally, had a phone interview after 3 weeks of application. It was like a typical screening interview touching various topics on networking and system (linux). Then I flew to Seattle and had 1:1. The onsite was 2 hours technical and then managerial/behavioral of 30 mins each. The good things is not only they pay for the flight but also the taxi, meal etc.

    Easy Interview

    Application

    I applied online. The process took 3 weeksinterviewed at F5 Networks (Lowell, MA) in September 2014.

    Interview

    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.   1 Answer

    Negotiation

    Very convenient. I was happy with the offer provided to me.

    Average Interview

    Application

    I applied online. The process took 3+ monthsinterviewed at F5 Networks (Boulder, CO) in April 2014.

    Interview

    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.   1 Answer

    Negotiation

    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.

    Average Interview

    Application

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

    Interview

    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

    Negative Experience
    Average Interview

    Application

    I applied online. The process took a weekinterviewed at F5 Networks (Seattle, WA) in January 2013.

    Interview

    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

    Interview

    Phone Screen followed by in person interview. This will be a panel interview over the phone and in person. Basically you will interview with about 7 people in the span of 3 hours. The questions are detailed and grueling, but they are only probing to see if you might be better suited for a more advanced position (ENE or EAE)

    Interview Questions

    • Linux CLI questions and Extremely detailed TCP/IP stack questions, HTTP questions and SSL questions. Know these backwards and forwards.   Answer Question

    Average Interview

    Application

    I applied through an employee referral. The process took 4 daysinterviewed at F5 Networks (Seattle, WA) in October 2011.

    Interview

    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.

    Average Interview

    Application

    I applied online. The process took 1 dayinterviewed at F5 Networks (Spokane, WA) in November 2010.

    Interview

    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.   2 Answers
    • What is the TCP/IP handshake process? or something like that...   1 Answer
