We hire by competencies, not age/seniority. We hired an 18 year old security hacker for the summer between high school and when he started at Stanford, for example: https://www.marketplace.org/2017/08/10/tech/17-year-old-hack...

That said, most of the engineers we hire have done things like stand up large web-scale services, deploy things to the cloud, and often have some good scars/stories/experience as a result.

Whether it's a good fit now or down the road, I really like that you're using mobile app interaction traces to look for UX insights that can improve things!
