When I interview someone and they are scared of `git rebase -i` it's a huge red flag.

Git rebase has such foundational data structures and concepts that you couldn't pass a serious college programming course without grokking it.

The only reason someone would be scared of git rebase is:

  a) they don't know the basics of programming/software engineering
  b) they are not intellectually curious enough to look into how tf the software they use every day works

You probably shouldn't have engineers like that on your team.
