It's easy if you've coded enough to know. I hate the fact that in Python, to reverse a string, I have to do slicing:

string[::-1]

In Ruby, I can do string.reverse() so that makes me hate that about Python, well... that and a few other things, but otherwise I love it.

I think he's looking for knowledge enough to know what you would do differently if you could change the language. Otherwise, you're not interviewing a qualified person.



I can tell you plenty of things I would do differently. But I probably couldn't think of them right off the bat.

For example in python I'd change how function references are passed around. Especially in regards to passing them around to children processes.
