One of the best techniques to employ during the interview process is that of a written portion. For us, we have a series of research questions that aren’t easily answered without effort. It helps us understand the candidates’ writing skills, resourcefulness, and attention to detail.
In addition, being a SaaS company makes it easy for us to provide a few simple assignments for the candidate to do using our web-based software. This helps us better understand how quickly they pick up new products, their resourcefulness, and their likelihood of success in the company.
I recommend using a variety of different techniques to assess candidates.
