What are some of the patterns you've used when hiring students to ensure they fit into the company and become productive as quickly as possible?
Two filters could be conducted for help identifying students fit your team.
1. Pre-work or After-word to the interviews. Sometime I require the student candidate to do some work before or even after the interview, to know some special aspects of their ability, and most important, how they treat work.
2. Internship before actual official work, this can give both student and the company better insights each other.
