They first contacted me on LinkedIn, then an interview to assess my English level (I'm from Venezuela), and then an interview with one of their data scientist. They liked my profile, so we went to the economic offer which I could negotiate successfully. After that came the interviews with their clients. In the first case, it was a more programing leaning role, so it wasn't really a good match. They always kept me very well informed about the process. About a month later, they contacted me for another client, and this time there was a better match, so I ended up with an offer.
