F5 Networks Interview Questions & Reviews

Interview Details Basic phone interview regarding past projects and experiences followed by on-site interview with a tech lead and unknown. The tech lead seemed nice and was asking both technical questions and about previous projects with accent on the sockets / threads management. The unknown was very unpleasant, was constantly going in/out of the room or talking on his phone.

Interview Details Phone technical screen by HR. Interview loop consisted of being interviewed by technical, managerial and director personnel. Each was roughly 1 hour in span in a meeting room followed by a follow up with HR.

Technical interview was the standard sort to prove competency with Unix and Networking.
Managerial interview involved conflict resolution, work flow, time and issue management
Director interview involved more intra-workplace conflict resolutions and career discussion.

Reason for Declining – It wasn't a position I was in love with and they understood that. Was very happy to spend time with them and would work there if a new position that fit did arise.

Interview Details First Contact from HR - a quick 30 Min interview covering basic TCP/IP and Linux
Booked for a second tech interview. Two engineers drilled into the details of TCP and almost two or three qns in every osi layer. Then a bunch of question on Linux OS. Questions were asked about the basic CLI commands

Interview Details Interviews are generally split into several phases - phone calls with potential team members first, then on-site day long meetings with broader organization.

My interview was non-existent, I was a direct hire as a result of a long relationship external to the organization.

Negotiation Details – I said I'd like X, they returned with how about X plus bonuses/stocks? I said yes.

Interview Details HR manager interview -> Technical interview

Interview Details I was initially contacted by email, to setup a phone interview. The phone interview was standard technical questions. I was contacted later that day to schedule an in-person interview. It was a panel review; an Engineer handled the technical questions, while three Managers were asking other questions. The Managers are always trying to get you to say something negative; be it about yourself, another person, or another company. Don't fall for it.

Interview Details Applied online, got a response within 2 days which was quick. Passed the initial phone interview. Then scheduled pretty quick for an onsite interview. The interview was a whole-day event. It started with a coding test which was easy. They mainly look at C programming basics. After that I was interviewed by 6 engineers + 1 manager. Almost all of them came with a paper having 3-4 coding questions per interviewer. I found that odd given that I already had a coding test. Some of them did look at the resume, but it was mainly an interview to see how quickly you could code. Most interviewers did not give me to ask any questions which was very odd. Also I think they need to look at the candidate before firing 3-4 coding questions (string, bit manipulation, etc).
If the candidate is a junior engineer I can understand. But if the candidate is having 10+ years of experience, I expect a bit more design questions rather than how quickly you can crank some code on the whiteboard. Most of the interviewers ended up asking the same questions, which I politely pointed out.
I did very well in the interview, but for me I did not feel comfortable with the process and the people. All seemed to robotic and there was no "warmth" or "welcoming feel". Did not seem like a nice place to work.
Also did not receive any feedback after the interview.

Interview Details Meet with each inside sales management of 3-5 people. Big question is "Why F5?"
Be prepared for 30-60-90 plan and how you plan to execute
Energy and positivity are key in the interview. F5 has a great culture and fitting into that culture is very important.

Negotiation Details – Too good to turn down with initial offer. No negotiation necessary

Interview Details A technical interview is often made up of 5 to 6 technical interviews that last close to one hour and a lunch with the managers in the middle. Interviews are a combination of what is on the candidates resume and technical questions. Questions vary depending on the group and interviewers.
