Interviews by themselves are not sufficient for thoroughly realizing your connection with a potential candidate. It takes at least three of the following steps before you can even scratch the surface:

Vocational Interview – classic meet and greet to dissect the position together.
Social Interview – drinks, meal, exercise or games to test a cultural fit.
Portfolio – collect samples of past work like writing, formulas, apps, design, etc.
Shadowing – an observational half-day tour of the office, team and work ahead.
Co-Piloting – a hands-on tour of the job, shared and observed in part by an employee.
Contract Work – full trial of a person’s skills and autonomy to complete a project.
References – a second opinion from people who worked with the candidate before.

The more involved your interview process is, the better. Candidates who make it through show true dedication to the position ahead. There’s always a way to work with someone in advance of hiring them, even if it means tours or co-piloting after hours or remotely.
