Solicité el puesto a través de la escuela superior o la universidad. Acudí a una entrevista en Rakuten (Boston, MA) en sept 2018
Entrevista
I met with a recruiter at my school's career fair. He gave me a take-home problem set with three questions to solve in three days and email back to them. Even though I was applying for a data scientist role, the questions were very CS-heavy. In particular, the first question involves writing a function that finds the minimum spanning tree of a directed graph. If you look this up, you'll see that the algorithm for this is quite elaborate and basically impossible to come up with by yourself, especially if you're a data scientist not a software engineer. Nevertheless, I answered all three questions to the best of my ability and emailed my solution and resume back to them. Then it was radio silence for a month. No one even acknowledged that they received my solution, which took me three days to write up because the problems are by no means trivial. I emailed them again to follow up. Still nothing. It was a huge waste of time.
