7 months process, long interviews with a lot of requirements: project presentations, interview with data scientist, data scientists manager, data analytics manager, etc. They asked me to do all the bureaucracy for moving to Abu Dhabi and conditioning my personal life for all this time for, finally, ghosting me and telling me that the position was closed and they weren't going to hire me. They didn't compensate the expenses of all the translations of papers to Arabic, transportation costs to Madrid and staying there for 3 days and high personal costs related to family and friends.
