I applied online and they contacted me after 3 months. They was seeking for a data scientist to work remotely with a US based team. first, i met with a local manager in Tunisia. Then i had been interviewed by my manager in the US ( by Skype) . We had a long conversation, after this long process, they didn't send me any message, which was not very professional . I taked the initiative to reach out the recruiter who informed me that the interview was pretty good, but the position was canceled !
