"Beyond doing blind references — which have saved us in the past from hiring people who turned out to be lying to us in interviews — I've found that I learn the most from a candidate when I ask them a bit of an uncomfortable question," says the co-founder and CEO of WayUp. "I like to see how they react and whether they're able to stay calm. I don't do this because it's fun. I do this because I want to see whether they can keep their composure and how they perform when they're out of their comfort zone, which is often the reality in the start-up world.
"Sometimes, I just push back on something they designed or created and play devil's advocate, to see how they react to different opinions. Other times, I ask questions like, 'Why would someone not get along with you?'
"Flexibility is so crucial when you're working in a fast-paced environment like a start-up because things change really quickly. The people who succeed will be the people who can shift gears when needed."
