I joined Google straight from college 6 years ago as a SWE, and by now I'm used to the style of work of "do the minimal work possible to do the job", I never challenge myself to deeply learn about what I'm doing, it's almost like I've been using only 10% of my mental capacity for work (the rest was on dating/dealing with breakups/dealing with depression/gaming/...).
Even when I get a meaningful project, all I do is copy code from the internal codebase and patch things together until they work. I was promoted only once.
Now that I'm thinking of jumping ship to other interesting companies, I'm having serious doubts that I really learned what I should have learned during all those years. Especially since I'm considering companies with a higher hiring bar than Google.
How can I keep myself accountable while I'm still at the company to deeply learn the FE/BE technologies to be better prepared for other companies? Should I start by preparing a checklist of technologies and dive into each of them for a month and continue from there?
