For much of my career, I worked a normal 40 hours a week or so schedule - I did do coding outside of work, but on open source work or projects I wanted to do. Those outside of work activities were only when I was interested in doing so, and had no effect on work.
I became a senior frontend engineer in about 1 1/2 years.
that's pretty impressive! how do you make sure you're not getting too specialized within the company and are actually advancing your cs knowledge instead of the product knowledge?
