    Easy Interview

    Application

    I applied through college or university. The process took 3 weeks. I interviewed at F5 Networks in June 2015.

    Interview

    phone interview with recruiter then with 3 other people. They had this online coding website link to share the view of me writing the code. All 3 people asked technical questions then coding question for last 20 minutes. The interview was pretty long, I would say around 3 hours. I was not really prepard for behavioral part (articulating my past experience) so it was a minus for my 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.

    Average Interview

    Application

    I applied through an employee referral. The process took 3 weeks. I interviewed at F5 Networks (San Jose, CA) in May 2015.

    Interview

    Recruiter called to setup a phone call with the hiring manager. Several days of silence then sudddenly a date is fixed and the hiring manager calls you for initial phone screening. Pretty simple stuff like C++ templates, iterators, SSL, difference between active and passive FTP. Since I already had an offer from another company and had to make a decision so pinged the recruiter and she quickly setup an onsite interview. It was a lengthy onsite process in which you ended up talking to 5-6 engineers and the hiring manager as well.

    Interview Questions

    • 1. C++ exception handling , copy constructors and many questions on C++ templates. Most of the interviewers were obsessed with templates and they want to dig into it.
      2. Templatized linked list.
      3. One of those senior guys came and started with a "warm up" question on network latency and from there on a barrage of questions...
      4. Hiring manager asked questions on iterators and a white board coding on converting a byte stream into hex string.   1 Answer

    Security Engineer Interview

    Average Interview

    Application

    I applied through a recruiter. The process took 2 weeks. I interviewed at F5 Networks (Seattle, WA) in May 2015.

    Interview

    The interview Process began with an initial phone screen by a recruiter. She scheduled a group interview over webex with a team of individuals. This actually worked out quite well and the interview went well and was pleasant.

    On my 3rd round of interviews, I was scheduled via web ex with two individuals. One of them began the interview by saying, "I see you worked in Washington DC. Well we all know that they don't do any real security engineering there, but I guess we have to do this interview anyways." Dead serious. Then he started asking technical questions, none of which were related to the job, just technical questions to quiz me. During me answer he'd have a side discussion with another person in the room. When I'd finish talking, he'd say, "okay yeah...." and go to the next question. He wasn't listening or paying any attention. He was exceptionally rude. I was glad when the interview was over.

    There was no further communication from F5 engineering or recruitment after this encounter. I accepted an offer from another major tech company in the area.

    I applied through an employee referral. I interviewed at F5 Networks.

    Interview

    Fairly quickly. Applied and received a request for an email the next day, interviewed the day after that and got the offer the day after that. Very fast process. Having someone on the inside helps. You essentially go through 3-4 interviews within a 2 hour block of time; you meet the hiring manager and individuals from whatever team you'd be working with.

    Interview Questions

    • There wasn't any formal questions...it was more or less the interviewers trying to get to know you better as a person so just be yourself and answer anything they ask honestly. be sure to ask follow up questions as well.   1 Answer
