You go through several emails and questions. They start by asking you to answer 3 questions about yourself and your motivations.
Second email they are going further about your skills and the tools you use, also they ask you to pass a personality tests.
In the third step, it's a case study based on their problems and vision. (Never do this for free, I'll explain at the end of this review)
Fourth step, you get a video interview (I was a foreign candidate)
After all that, you receive nothing.
Not a Yes or No. They simply ignore you.
I might be not the right candidate but They could send at least a simple email saying, you are not the perfect candidate for us.
Ps: If you apply for them, Never do the Case study exercice, at the risk to see your strategy used for free and you, ignored.
