    Senior Product Marketing Manager Interview

    Anonymous Interview Candidate in San Jose, CA

    Negative Experience
    Easy Interview

    Application

    I applied through a recruiter. The process took 1 day. I interviewed at F5 Networks (San Jose, CA) in September 2016.

    Interview

    Their in house recruiter contacted me via Linkedin. I had a phone call with him just out of curiosity. He asked me if I knew of F5. I work for their top competitor in the same role. He should have know this. I'm also connected via Linkedin to many of their management team who I know from a previous job, which I brought to his attention. This didn't seem to register with him. He then asked me if I've ever written whitepapers. That's like asking me if I've ever sent an email. I've written dozens and dozens of whitepapers. He could have looked at my blog that is linked to on my LinkedIn and discovered this or he could have looked at my Linkedin Posts and seen that I have very relevant expertise. He then went on to tell me about how many whitepapers I'd be expected to write for them. I asked him what they needed the whitepaper for but he didn't have any idea. He then asked me about pay and I gave him my range. He said that I was high. I told him how I had proven successful experience with marketing the same type of product to the service provider market that they were trying to break into and that his type of experience was quite rare and valuable. This information didn't register with him. I told him that if they wanted to have a discussion of what it would take to be successful in this role I'd consider that. I never heard back.

    Senior Software Engineer Interview

    Neutral Experience
    Average Interview

    Application

    I applied online. The process took 1+ week. I interviewed at F5 Networks (Seattle, WA) in June 2016.

    Interview

    Initially just did some phone calls with management and HR people, sounding one another out about what the others goals were. I have an interest in low level software which seems to dovetail well with F5's product line. I felt there was a good match. I'm a senior person with a lot of experience from serial and video drivers up though system management of these devices as well as lots of network experience.

    Next I was invited in for a day of interviews. I generally get nervous during interviews and don't think well. I had 2 technical interviews where we chatted about goals, products experience etcetera leaving about 30 minutes for the coding questions.

    After the tech interviews, I went out to lunch with the managers who initially seemed interested, but cooled as we talked. I expressed interest in low level stuff, but I think they're more interested in exporting that code to a service environment.

    The next day they were good enough to call and obliquely inform me I didn't get the job because they had found a better fit with assurances that I was the right guy for F5.

    I've contacted them subsequently with no reply.

    Applied via a reference. Normal process, online app, phone screen, in person interview. Strong showing by f5 nice offices, smart people. Overall very professional approach and comportment.

    • What creative recruiting methods have you used and why ? It did not seem like the HR Business Partner had their heart in the call - just went through the motions.

    Business Development Solutions Architect Interview

    Negative Experience
    Easy Interview

    Application

    I applied online. The process took 3+ weeks. I interviewed at F5 Networks (Seattle, WA) in March 2016.

    Interview

    I applied for the job in early March 2016. I got a call from the hiring manager about 3 weeks later. We chatted for about 30 minutes and it went well. HR then scheduled an onsite interview the following week with 4 people including the hiring manager. The process thus far was very professional. I met with two would be coworkers; an engineer and solution architect and they were very friendly, they didn't ask very many questions. The hardest question I got was "tell me about the OSI model." I did most of the talking but it was only 30 mins each person, so not enough time to get into anything deep. Then I met with the hiring manager's boss, I really liked him, nothing technical there. I then met the hiring manager, and I immediately felt like something was not right. He asked my almost no questions, he was very cold and I was supposed to talk an hour with him but only talked 30 mins. He was not personable at all and very difficult to read. At the end of the interview he said, "well you are 1st person we interviewed, we will get back to you." I then spoke with HR for a couple of minutes and left. I followed up with a thank you, not response. I followed up again when the hiring manager said he would make a decision, no response.

    Dear F5, if someone takes the time to submit an application, prepare for an interview, come and spend a half day of their time with you, have the decency to respond!
