The selection process was quite quick and smooth: I sent my application via email to my future supervisors. They replied quickly. The job for which I applied was not available anymore, but my future supervisors offered me to discuss on another job/subject, which was close to the one I applied initially. I accepted, and we had a Skype interview. 10 days later they offered me the job. However, the administrative part was too slow, it took a long time for them to send me the contract and visa application, which delayed my 1st day of work, and also made me buy my flight tickets quite late (I came from Europe) and increased their cost.
