Why I Always Ask To See Code

The quality of code is a reflection of the environment in which it was created. Chaotic environments usually create chaotic code. Professional environments usually create clean code. In my experience, it's one of the most reliable metrics that you can check before taking on a new client, employee or employer.

So ask to see code. Scan through it. Try to build and deploy it. Try to write a test. It only takes a few minutes and you can learn a lot.
