First-hand accounts from people who interviewed at F5.
Program Manager
I had a phone screen with a recruiter who seemed unprepared and unsure about the role. She didn't have questions ready and didn't seem to know how to interview for the position. She spoke for most of the 30-minute call, leaving me little time to share my examples. She spent the first 7 minutes giving me unsolicited feedback on my resume. She only asked me one question about my experience. I'm not sure if she disliked me from the start, but it was unprofessional. I didn't expect to move forward, and I never heard back from her. Given the company's size, I was disappointed by her unprofessional conduct.
- Could you provide some examples?
Technical Intern
It was an on-campus interview. The first round was a technical interview. Then, there was a technical managerial and an HR round. The first technical interview focused on my resume, asking about cloud technologies, load balancing, virtualization, OOPs, OS, and my prior internship. The second technical interview covered security, networking, and cryptography. The HR round was general, assessing eligibility and adaptability.
- Can you introduce yourself?
- What is virtualization?
- What is a container?

Software Engineer Intern
The interview process has three steps to showcase your skills and get a chance to work in a dynamic and collaborative environment. First, you submit your application and resume online, which are reviewed for basic qualifications. Then, if selected, there's an initial phone screen with a recruiter to discuss your background, career interests, availability, and technical skills. After that, you might get a technical assessment or coding challenge (like solving problems or debugging within a time limit) to check your programming and problem-solving abilities. Finally, successful candidates move to technical interviews with the engineering team, where you'll discuss technical concepts, algorithms, data structures, and software engineering principles, possibly solving coding problems or explaining your solutions.
- coding assessments
- leetcode problems
- three stages

Make sure to correctly handle cases where '%' itself is encoded as %XY (e.g., %89 for '%') and re-convert the output if necessary.”
