Security Consultant Interview

Anonymous Interview Candidate

I applied online and interviewed at F5 Networks.

Interview Details – Found the job listing on the F5 website, and sent my resume via email. The next day I had a message in my inbox from a recruiter who set up an initial screen. She called me the next day and took about 15 minutes of the usual get to know you questions. She emailed me later that day with info on another call with the hiring manager. The HM called me and took about 20 minutes of get to know you and some initial technical questions. He then set me up with a senior technical member of the team for a technical interview. Interview lasted about an hour and was very technical, all over the phone. I later received an email stating that my knowledge wasn't deep enough and would not be going any further.

Interview Question – The most difficult question was asking about access group policies on a ASA firewall.   Answer Question

Very Easy Interview

Senior Technical Marketing Manager Interview

Anonymous Employee

I applied through other source and the process took 3 days - interviewed at F5 Networks.

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.

Interview Question – Did not receive any.   Answer Question

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

The process took 4 weeks - interviewed at F5 Networks in May 2012.

Interview Details – Hour long phone interview, pretty standard questions, nothing tricky. Then 3 hour long interview with 4 members of the team. Interviewers were dressed business casual and rotated every 45 minutes or so. Again questions were typical interview questions. Why f5? What do we do? What are your goals in 5 years?

Software Engineer II Interview

Software Engineer II
Seattle, WA

I applied through an employee referral and the process took a day - interviewed at F5 Networks in August 2012.

Interview Details – My interview was more on the Front end development side (Web development) After an Initial phone screen, where everything went pretty smooth, I was called onsite.
I had a total of 5 panels and the people who interviewed were pretty cool.
My first interview was with the Director of the team who asked me all non technical questions, this was more about knowing my background and my past experience.
In my second round I was interviewed by a UI designer who asked me questions related to the UI design principles. It was not much difficult and it was not a typical interview where people drill you with questions. I showed them my portfolio of what I did in my previous job and explained about them. Most of my time went in that, so there was not much time to have that question answer thing!
Later, I was interviewed by my manager, which was a proper interview ;) He asked me almost about everything... Right from backend till the frontend, but the questions were very basic and straight forward.
My final interview was with a Senior Software Engineer, who asked me Javascript and JQuery related questions.

Overall, the interview went pretty well and the people were pretty cool. You will not feel like you are getting drilled by gazillion of questions, it will be more of a conversation and discussion more than a Q&A round. So be confident, get your portfolios and be ready to explain everything from your resume!

All the best

Software Engineering Internship Interview

Anonymous Employee

I applied online and the process took 4+ weeks - interviewed at F5 Networks in January 2013.

Interview Details – I applied online and had a phone interview scheduled within one week.
I spoke with the hiring manager for a half hour or so. She wanted to see whether or not my resume was accurate and mostly asked questions about prior projects, languages I knew, and how I go about solving a problem.
After one week, I heard back from my recruiter who wanted to bring me on site for an interview. I had five interviews with four people and it took 3-4 hours. I was asked about many things including behavioral questions, past projects, classes I was taking. Some interviewers went through my resume and asked me about the things on it. They would drill deeper to see if I really had a good understanding of CS concepts.
Basic software engineering experience and knowledge of software design practices are important. Knowing multiple languages helps.

Good problem solving skills are critical for interviewing at F5. It's okay if you don't know something, but you need to demonstrate you could solve a problem you know nothing about.

Overall, interview process was good and the people were quite friendly and supportive. I got a tour of the facility and met many of the people I would later end up working with. There were no trick questions or really difficult problems. I don't think I was asked a single question I didn't know the answer to. If you're a good fit for the job, you shouldn't have problems here.

Interview Question – I didn't get any tricky technical questions, but I was surprised when I was asked for my favorite data structure.   Answer Question

Negotiation Details – Rate was good, did not negotiate.
