// Programming Challenge: Launch 4 threads, goroutines, coroutines, or whatever your language uses for concurrency,
// in addition to the main thread. In the first 3, add numbers together (see sample code below) and pass the results
// to the 4th thread. That 4th thread should receive the 3 results, add the numbers together, format the results as
// a string (see sample code), and pass the result back to `main` to be printed.
//
// Do this as succinctly and readably as possible. _Go!_ #golang #programming #concurrency #challenge

A lot of these are outright stolen from Edward O'Campo-Gooding's list of questions. I really like his list.

I'm having some trouble paring this down to a manageable list of questions -- I realistically want to know all of these things before starting to work at a company, but it's a lot to ask all at once. My current game plan is to pick 6 before an interview and ask those.

I'd love comments and suggestions about any of these.

I've found questions like "do you have smart people? Can I learn a lot at your company?" to be basically totally useless -- everybody will say "yeah, definitely!" and it's hard to learn anything from them. So I'm trying to make all of these questions pretty concrete -- if a team doesn't have an issue tracker, they don't have an issue tracker.

I'm also mostly not asking about principles, but the way things are -- not "do you think code review is important?", but "Does all code get reviewed?".
