The process consisted of a 30 mins interview over Skype, structured in three parts mainly: company introduction, past experiencies conversation, questions.
They clearly didn't know what to ask, so resorted to asking about the very last activities I'm working on. Which makes no sense: why is only the most recent experience useful? It's not necessarily the most challenging, interesting, beneficial, relevant, formative. For me it was not, and was the least relevant to the job. The funny thing is that I had relevant experience for the job that they didn't go through. No technical question anyway. But the most shocking thing was the very last question on having experience with Linux: I have been using Linux for a very very long time, daily, it's almost exclusively the only OS I work with, I've contributed to drivers (the source code is public), I've written many tools and libraries on top of Linux. And it's all in my CV, the same CV that was sitting on their table but that they didn't bother reading. Unprofessional.
On the positive note, they have been fairly honest in admitting they don't have many customers when asked.
