Welcome Briefing; A presentation from you lasting 5 minutes; a very simple group task in which I suppose they will analyse how you fit in a team, what type of role you adopt, your communication skills, etc,; an individual Logic Test with some simple math questions, and then other coding questions (any basic/ fundamental knowledge of Phyton/R should be sufficient to answer to these!); A very elucidating presentation about Merkle and the role followed by brief individual interviews. Everything happened quite fast, it seemed rushed, and they didn't get the time to deeply get to know any of the candidates. Seems to me they are just trying to hire in bulk.
