- How do you refactor code?
- How do you navigate code (e.g. Eclipse will let you click on a class and it'll find the appropriate source file if available)?
- Do you have a sense of whether using vim vs. an IDE affects your efficiency or correctness?
- Do you have an equivalent for things like autocomplete, intellisense, organise imports etc.?
- What are IDE users missing out by not using vim?
- What kind of code do you write e.g. is it a small number of heavily optimised classes or a large number of, say, feature driven classes?
