Ho presentato la mia candidatura tramite un selezionatore. Ho sostenuto un colloquio presso 3Red Partners
Colloquio
Somewhat standoffish / distracted interviewer. It was a coding / technical interview but it was clear he was doing it from his phone. Asked language-specific questions, very specific data structures (in the above language) questions, algorithms questions about numpy internals, and ds&a questions.
