How should I pick a web application software engineer?
We can go so far as to write the whole thing in a single page, but don't have to. It would pretty much all be written by the web application software engineer in question. The exact open source libraries to use is also up to the engineer, within reason.
I'm specifically looking for advice on what qualifications to look for/verify in an interview, since picking a web application software engineer in general is just too broad a topic.
