Maybe you should be using `git stash` and `git stash pop` rather than commits. Or go back and squash your 30–50 commits into one or two, which might take ten minutes. What you're doing is better than not using version control at all, but only barely.
This is what senior engineers do. Interrupted to switch tasks every 10 min. Make your good changes as a commit and move to the next task. Maybe you get back to it today, maybe not.
That's definitely not how Jeff Dean and Sanjay Ghemawat wrote MapReduce and Bigtable. I'm sure what you're saying is correct at many companies (I've seen a few), but it's a stupid policy, depriving them of the benefit of having senior engineers.
