    Difficult Interview


    I applied online. The process took a weekinterviewed at F5 Networks (Chertsey, England) in November 2013.


    I got an initial email from the recruiter (HR), then scheduled with the same HR employee a quick 30 minutes interview, with simple and less-simple technical questions - no personality test. I did well, so I qualified for the second round: One hour of tougher technical questions with a support engineer. This is CCNA level and beyond (all 7 layers of the OSI model and the full TCP/IP stack) plus Linux.
