Easy interview, free discussion, nothing special overall. If you know some linux + probing you`ll be fine. You should tell them a good story about your experience and what situation you have it.
I applied online. I interviewed at Vodafone (Porto, Oporto) in Nov 2022
Interview
The first interview was super simple process, just the common questions about your experience All the process was made with a good enviroment with all the people. They understand the fact that I don't have a lot of experience.
