    Interview

    I handed over my resume to them at a career fair which was held at school. After about a month, they e-mailed me to confirm my phone number. I scheduled an interview with them via phone call, and the interview was on campus. After that, all contacts were by e-mails.

    Application

    I applied online. The process took 2 weeks. I interviewed at F5 Networks.

    Interview

    I've applied online and heard back within 2 weeks telling me that they would like to schedule a 45 minutes phone interview with the hiring manager. After that, I've been invited to onsite and had two onsite rounds and one written coding test. I can't tell the questions because of NDA but I could say overall they've tried to touch every area that you might know.

    It seemed like they were interested in what you know and how you think. They never say enough, as soon as you keep talking and solving the problem, trying to figure out how much you know. I've had two proper coding questions on board and one data structure design question for a given problem and two open ended problem solving and past experience related questions. There were also behavioral questions.

    At the end of the second round, the recruiter came and said they wanted to move on and give an offer on the spot. I was caught off guard but was happy that the process was faster. The whole process (two rounds and offer, excluding the time between phone and on sites) took a week.

    Negotiation

    I was able to negotiate as I had several other offers but the package offered was good and competitive. It had a slight edge.

    Difficult Interview

    Application

    I applied through college or university. The process took 1 day. I interviewed at F5 Networks (San Jose, CA (US)) in August 2011.

    Interview

    Interviewer asked questions mainly on technologies I was not familiar with. I told him that I didn't know those technologies, but he still proceeded with the questions, which makes me think he had a set list of questions and wasn't prepared to alter the interview based on the applicant.

    Easy Interview

    Application

    I applied online. The process took 2+ months. I interviewed at F5 Networks in January 2017.

    Interview

    I applied in mid December 2016. And I was contacted by f5 recruiter in Mid January 2017. Recruiter setup interview with a Software Engineer. The interview lasted for about 20 - 30 minutes. I was asked to write a simple C program on collabedit.
    At the end of the interview, the interviewer gave me a positive feedback. He said I should expect to be called for on-site interview. After a couple of days, recruiter reaches out to me and asked me for my availability for on-site interview. After I sent him days/times, he replied saying that he made a mistake in his previous email and that he has not received a final decision yet for my interview from the hiring manager. It could be a genuine mistake but, imagine how you would feel to be told it was a mistake after you rescheduled other interviews for this one. I emailed the recruiter a few times and he told me there is no update. Then in late March 2017 I received a generic rejection email.
