The interview was 1 hour and 30 minutes with questions about testing an Authentificator with id and pass, basic commands in Linux, networking (OSI Layers). For the linux part they want you to share the screen and do some tasks with files. Also i had a technical online test before attending the interview with around 30 questions in 30 minutes. The overall difficulty was medium and there were no scripting / programming questions even though i was told that i have to know OOP for this job
