Code/tech questions I've been asked
By Steve Claridge on 2025-08-24.
I thought I'd start compiling a list of tech-related things I get asked. I'm a senior engineer and so often get asked coding/architecture type questions at work. I also tend to get quite a lot of general app/entrepreneur/startup type questions when people learn I've run a few companies over the years.
Seeing as writing is learning, I thought I'd start to put some of the questions into words on here.
