I applied on their website. 2 weeks later I followed up a mail to the company and I was finally contacted by the sales manager (which was exceptional because it's normally the recruiter who calls first). It was a very good experience as the sales manager wanted to build a sales team and he was very pleasant to speak with.
Next step, I had a skype interview with the recruiter. That was a standard interview. It went well.
Next step, I was finally asked to prepare a case study 1 week later. And everything went very well.
Next, I call the sales manager and the recruiter for again about the next step. But they couldn't hire more people at that time.
