F5 Engineering interview questions

Applied online. Got call from recruiter. Set up phone interview with hiring manager in few days. Manager was very friendly. Explained about company. Asked my experience related to requirements of the position and interest in position and about the company. Asked some problem solving (DS/algorithm related) questions. They see how you approach it. Not the exact answer. Next round would have been coding related interview with team members onsite. But couldn't clear the initial screen.
