Interview with Qualys was very good experience, For Technical Support Engineer Position, I was having 3 rounds of interview, 1st & 2nd Round were Technical Round, 3rd was Managerial round. For 1st & 2nd round they send a list of topics to cover for the interview, most topics covers concepts of Networking, Operating System Windows/Linux, Security Concepts. The topics were all basic concepts of Networking, Security & Operating Systems. Anyone who is already familiar with these topic would not have any problem. 1st Interview was mostly basic questions related to these topics like "What is this topic, Concept?", In case of 2nd interview most of the topics were same as 1st interview but during interview they ask deep questions related to the concepts to test your understanding of the concepts. 3rd round was mostly basic questions related to you, your previous experience, etc. Nothing serious about 3rd round. Overall Interview was not that difficult anyone having background related to Cybersecurity could easily crack the interview.
