I applied online. The process took 2 months. I interviewed at F5
The recruiter contacted me via text, then I had a screen call with the hiring manager. After that, I was invited to interview. The interview was four rounds with one panelist per interview. The questions were mix of situational experiences and problem solving.
- Q: Tell us why you are interested in this role?

Anonymous Interview Candidate
The process took 2 weeks. I interviewed at F5
The overall impression is quite disappointing. The recruiter didn't even took the time after i went through to 3 interviews to communicate the results or feedback (negative I presume) after the technical interview. Management and techinical people seems to live in different worlds and seperate from any shared information. Did 1st interview with management which was ok, i had still some question, like who is the team, which project i will work on. I thought the technical interview would give me clarity, but Principal engineer i spoke, didn't know either which team/project I should work on. The principal engineer asked me to do coding session(there was on preparation link or video), which was not really clear announced in mails, from a Principal/Senior person, I would expect more a system design and high-level interview, but it was the "usual" college coding games interview which most of time , Senior people have difficulty to answer because nobody use them in real life and junior people excells Disappointing from the technical interview to the recruiter, I diddn't felt my experience was valued. Sad that is always the tipical way of filtering people. I would not reccomend The manager I spoke with allthough was kind and with experience
- Code a function which do a background process and take some data as input, etc

Anonymous Interview Candidate
I applied through college or university. I interviewed at F5
Two rounds both with a behavioral section and a technical question. First round was only 45 minutes, went a bit over time. Didn't reach the final round due to a backup of interviews.
- Describe a time in which you helped someone

Phone call with the recruiter, then a technical meeting and the meeting with the manager, then the offer was sent. The tecvhnical meeting was supposed to be just 1h, instead it lasted 1,5h. The process was rather short and simple.
- basics of linux, differences between tcp and udp, model osi, some simple coding excercises, how to schedule something to happen periodically on linux - I dont remember all of them but most of them were answered in most common linux interview questions

Anonymous Interview Candidate in Seattle, WA
I applied through a recruiter. The process took 3 weeks. I interviewed at F5 (Seattle, WA) in Oct 2022
Recruiter reached out to me via email and offered an interview. I did the technical interview and the engineer interviewing me was impressed. However, I received an email a week later saying that, although the feedback about me was very positive, they did not have enough spaces for me to continue in the process.
- How to find the square root of a number

Anonymous Interview Candidate in Seattle, WA
I applied through college or university. I interviewed at F5 (Seattle, WA) in Oct 2022
Phone Screen: Basic Behavioral questions One coding: backtracking questions Related to IP The interviewer is super nice and the whole interview is pretty smooth. It would be better to have some network background
- What is the cooperation experience Backtracking

Anonymous Employee
I applied through an employee referral. The process took 1+ week. I interviewed at F5
It was a technical interview asking questions on networking, experience in their products. And then a round for cultural fit. And finally the light managerial round to assess if my understanding of the role is correct
- When you enter a website on the browser, what is the process at the backend beyond that?

Anonymous Interview Candidate
I interviewed at F5
First one with HR - very friendly chat The second one was with 2 employees - One of them was REALLY rude and he was acting like he is taking me as a joke, the other one was really helpful but it felt so overwhelming with the other one I couldn't continue with the interview. I get into A LOT OF interviews before and it was the first one like this. Not sad or anything, I was just angry after the interview.
