When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

1. Begin with scaffolding a create-react-app, then update your package.json build script (replace DIR_TO_PHX_APP with the path to your phoenix app)

"build": "react-scripts build && rm -rf DIR_TO_PHX_APP/priv/static/build && mv build DIR_TO_PHX_APP/priv/static/build",

This will move your prod build files to DIR_TO_PHX_APP/priv/static/build on build

2. Run npm run build
