1:55:35boonetbe Q: I see quite a lot of people moving into more programming / software engineering related jobs after doing some academical research, not at all focussed on CE related things (physics, chemistry, etc). Do you have any experience working with people that didn't focus on coding for a long time, possibly not having any real training in it? What's the biggest difference with people that have a degree in CE or focused on programming from a young age?
