See that would definitely get you not hired ;)

Not because you use 2 spaces. You can argue 2 spaces and the pros and cons and how horizontal scrolling is an issue. One question back would be for example if that means you have huge run-on files where a single function does everything and that's why you need like 17 levels of indentation and that's why only using 2 spaces for each becomes important to you. And then you'd need to argue how that's better for visibility and what might actually be worse about it. If you can do all that, you're hired (if the rest of the interview goes well :P )

    Who still uses 8? Isn't that like a COBOL thing?
