1- HR phone call Approximately 30 mins for just getting to know you. What did you do, job description, what do you expect, etc. 2- Online test. Questions are from L2, L3 network, network security, firewalls, vpn, python, cloud, virtualization, web technologies. 3- Hiring manager interview. He tries to learn your capabilities and explains expectations. Nothing to worry about. 4- Technical Interview. I haven't seen any interviews like that. Expected time would be 60 mins, but it took 75 mins. Two guys asked questions one by one. It's mostly scenario based. The negative experience about it for example they asked me a question from my weakest point (such as HTTPs session steps), although I clarified I didn't know much about that, they asked additional 10 questions on that topic. That wasn't so fair. I almost answered more than %80 of all the questions, but they said you failed.
