    Application

    I applied online. The process took a weekinterviewed at F5 Networks (Chertsey, England (UK)) in November 2013.

    Interview

    I got an initial email from the recruiter (HR), then scheduled with the same HR employee a quick 30 minutes interview, with simple and less-simple technical questions - no personality test. I did well, so I qualified for the second round: One hour of tougher technical questions with a support engineer. This is CCNA level and beyond (all 7 layers of the OSI model and the full TCP/IP stack) plus Linux.

    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

    asinine impersonal lazy

    If you've ever had a phone discussion with a recruiter from Google, or Apple, or just about any tech company you're familiar with how they like to find good candidates and match them with teams that fit their skill sets. Recruiters that actually put a little effort into their job.

    Don't expect that with F5. F5 recruiters aren't even going to send you and email. They have an assistant who will do that. The assistant will schedule a time for a phone interview and that's about it.

    Then you'll have a phone interview where you are expected to write code on an online whiteboard. This is pretty common practice these days, but that isn't what is really going to happen. Your interview is likely to just hang up on you because he doesn't think you could write the code by looking at your resume.

    You can assure your interviewer that you read the job description and you have extensive experienced in every major area the job description lists. Give examples, sure, that might help. You can assure them that you you can work with the programming language he mentions. But you should just save your effort and pride and just say "Thank you. Have a nice day." because they couldn't be bothered to let you even attempt the coding exercise you were told to prepare for because they can't fathom how someone with your resume and experience could even begin to use the specific language they like to use.

    The recruiter will still not email you.

    Difficult Interview

    Application

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

    Interview

    F5 looks for the best. Not people with the right bullet points on their resume, but rather they look for people with an aptitude and hunger for learning. Most my interview questions were not product knowledge but questions that asked went in depth about advance technology concepts and also questions that made me have to think really hard rather than just regurgitating things from memory.

    More than anything else they were interested in seeing if I was a person that was constantly challenging myself to learn new things.

    Interview Questions

    • A theoretical question about traffic distribution for a product idea.   Answer Question

    Negotiation

    "We want to offer you X."
    (X was an enormous raise for me)
    I said "Okay".

    Application

    I applied through a recruiter. The process took 1+ weekinterviewed at F5 Networks (San Jose, CA) in January 2015.

    Interview

    Recruiter contacted me via LinkedIn. 1 phone interview with Architect. Mostly involved multiple programming questions and improving solution as much as possible. Got response after 2 days for an onsite. Onsite was 5 interviews with architect, principal engineer and senior engineers. Lunch with hiring manager. All the interviews were very good and very intelligent people talking straight about coding. No irrelevant questions at all. They tested algorithm and programming skills. After 3 days on onsite, got an offer.

    Interview Questions

    • Most of the interviews where about algorithms and programming in both JavaScript and java. They did let me know upfront the language they wanted me to code in. One interviewer asked mostly about system design and architecture for a web application with brief coding on each aspect of application.   Answer Question

    Negotiation

    Offer was decent enough according to my research so didn't negotiate.

    Application

    I applied online. The process took 2 weeksinterviewed at F5 Networks (Liberty Lake, WA).

    Interview

    Interview / hiring process is very thorough and detailed, and takes about half a day of interviews. They will keep asking you harder and harder questions until you stop knowing the answers. They are not trying to disqualify you, they are trying to see where your limits are. If you have sharp linux skills, and fair to middlin people skills, you can land this job.

    Negotiation

    There was no negotiation. They offered me the highest dollar posted on glassdoor for this position, and I took it.

    I applied through an employee referral. The process took 2 weeksinterviewed at F5 Networks (Northeast, NY) in April 2014.

    Interview

    Communication was great, the interview was staged into 3 technical interviews then a management level interview. The technical interviews all came in asking questions about real problems they were solving not just the theory BS that alot of places use. Management interview was lunch and just talking about various situations. Overall a very smooth interview.

    Interview Questions

    • Not difficult, but unexpected because I was interviewing for a python position was questions about javascript.   Answer Question

    Negotiation

    Initial offer was high enough I did not feel like negotiating so it was smooth.
