Solicité el puesto a través de un captador. El proceso duró 1 semana. Acudí a una entrevista en Chewy (Boston, MA) en may 2021
Entrevista
Technical assessment was sent via email. Questions were mostly pertaining to web development and Java. The assessment only gave around 20 minutes to complete. The questions were not difficult, it only took around 15 minutes to complete.
The interview was fairly straightforward, the interviewer asked questions relating to my experience and background, along with some generic technical questions relating to SQL and OOP. Nothing out of the ordinary.
