Is there a market for contract interviewers?
I believe there are fundamentally 2 big things to solve when it comes to companies hiring staff:
1) Finding the right people. This is a problem often at the "top of the funnel" where finding enough of good talent is hard.
2) Selecting the right people. This is a problem in the middle of the funnel where it can be really tough to determine whether or not someone can do everything they say they can, can learn quickly and strongly enough on the job to effective, and fit with the culture of the organization they're entering into.
I have heard of companies like InterviewStreet/HackerRank, Hire Vue, HireArt, and Talentex. I also know that a lot of companies do written tests (e.g. McKinsey), writing/portfolio samples, or recorded video interviews to filter people out without having to be in a room with a candidate or his/her teleconned presence. Nonetheless, I see most of these companies attempting to save more time on problem 1 rather than problem 2. I see problem 2 being especially difficult outside of engineering where assessing intangibles is often so difficult, and it can take 10+ hours of time per candidate.
To save companies time and effort, would there be a market for professional, contracted interviewers at least for first or second rounds?
