At 60, I applied to Canonical and got hired. The hiring process is thorough but very fair, all WFH, and they generally don't care about personal attributes. Gave me 20% above my asking price and a higher starting rank than expected.
I thought Canonical was the place where every candidate had to write a bunch of essays and talk about how they did in math in high school (regardless of how long ago that was).
Glad you had a good interview experience there, but it's genuinely the first time I've heard of it happening.
