Successful candidates complete > 20 hours of assessments during our hiring process (95% completion rate).
When we reject them we spend a significant amount of time crafting direct actionable criticism as a small sign of respect and appreciation for the time they spent with us.
One of my portfolio companies does three unusual things in their hiring process that has worked very well for them:
1) The first round is a reverse interview: instead of a hiring manager interviewing a candidate, the first conversation is one where the candidate asks questions about the company. It's used as an opportunity to pre-sell the candidate, who find it disarming & relaxing. Also, the questions a candidate prepares are revealing about the depth of their curiosity, and whether they're valued aligned. In some ways, it's more informative than a traditional first round interview.
2) The company lists roles that they are not actively hiring for, but likely will in the future. This lets them build a "waitlist" of quality candidates and ensures a much more streamlined process for those roles when they open up.
3) On the career page, there is small call to action with a link to contact the CEO directly for anyone who thinks they could be valuable to the team, regardless of whether there's an open role for them or not. A small but meaningful indication that the CEO stays directly involved in hiring across the company. There's also positive self selection in that the candidates who see that, take the initiative, and make an effort to reach out to the CEO, are more likely to be strong candidates & more passionate about the company.
