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

    Interview

    4-5 interviews. They were all good experiences. People were really nice and I learned something new from every one of them. They asked a lot of questions on networks even if you specify you do not have any background in the same.

    I applied online. The process took 4 weeks. I interviewed at F5 Networks in March 2014.

    Interview

    I applied online through their job listing and got a phone interview call in 3 weeks. The phone interview was as interactive one with a requirement of access to a computer so that you can demonstrate your programming skills for the asked questions on the shared screen (White Board). Questions mainly comprised of Networking basics such as difference between hub, switch and router; basic linux networking commands etc. Some other questions included data structure questions for C. Interviewer was nice and friendly. No reply after the phone interview.

    Easy Interview

    Application

    I applied through an employee referral. The process took 2 weeks. I interviewed at F5 Networks (Seattle, WA) in February 2014.

    Interview

    Interview process is longer than most other tech companies. Had 1 phone screen with the hiring manager about my current work and 1 algorithmic question. Had 8 onsite 1:1 interviews with a paper-based coding test. The paper-based coding test is what you would give to a college student. All interviewers were nice and friendly. All asked me 1 coding problem and 1 general question about either networking, OO programming or security. Not all interviewers asked me about my current work.

    Interview Questions

    • All questions were easy, nothing difficult. The interview process was too long.   Answer Question

    Negotiation

    Negotiation experience was bad. Its difficult to get them to quote higher salaries because they have hard set ranges for different level. This is a problem when you are coming from a big or high-paying tech firm. You would most certainly have to go for a lower pay.

    Application

    I applied online. The process took 1 day. I interviewed at F5 Networks (Seattle, WA) in May 2012.

    Interview

    I applied online and got the Phone interview. After the interview, there was no response for more than a week, and then got a call from a different team in F5 for another Phone interview. I was then selected to go onsite, where they decided to interview me for 2 different teams. Overall I was very confused as to what position they wanted to really interview me for. Onsite Interview process consisted of a coding test and then a 1:1 with members from different teams. Interview questions were standard, pretty much the same as the ones posted here. Few other questions, print binary representation of a number, how will you delete node from binary tree. One guy asked me questions in networking and he wasn't sure of the answers himself. He was clearly not a networking person, and rambled on TCP header and datalink layer header fields. Even after I tried to explain to him the actual field values, he wouldn't listen to me. They should make sure the interviewers ask only questions related to their domain.

    The process took 1 day. I interviewed at F5 Networks (Seattle, WA) in June 2011.

    Interview

    I submitted a resume through f5.com and didn't hear back for a good 4 weeks. At that time I had an initial phone screen interview which was pretty basic and more digging for experience. In a few days a 3 1/2 hour interview was scheduled where I met with various team members in a group interview setting. Questions included basic technical knowledge questions to white boarding various programming problems.

    Interview

    They give a typical computer science type interview. My advice is bone up on you basic algorithms and be able to regurgitate them from memory. Is is disappointing they don't ask any "real world" questions but seem to stick to questions that are easy if you studying your college text books the night before but harder if your college days were a few years back. You might be given a simple programming skills test. Bring a pencil, if they spend 5 minutes looking for one for you to do the test ,it detracts from your time to do it!
