I applied online. The process took 1+ week. I interviewed at DSR (Porto, Oporto) in Oct 2019
Interview
A really nice process with a long interview where I was able to know in advance what I'm supposed to do and how they handle daily tasks. Also, I was challenged to describe some of the previous projects I've been working in the past. The conversation over that topic made it possible for them to know what I like (and what I dont like!), driving the interview for the technicall requirements (some trivial questions about C and embedded related stuff).
Interview questions [1]
Question 1
About 10 C code samples and asked me what it does and if it is done correctly (simple stuff, and I'm just a novice - finished my masters about 2 months ago).
