What questions do you consider important for a Ruby on Rails technical interview?
i'm super confused by "which gems you can't live without". is this my personal debugging collection of pry-rails, bullet and other things? i mean, whatever is required and does the job i guess. i absolutely love Dentaku gem and build awesome stuff with it in 2 different companies where it absolutely contributed to their product in huge ways (https://github.com/rubysolo/dentaku) . i also love Victor (https://github.com/DannyBen/victor) where i draw epic custom charts which are used in reports that been generated for billion dollar real estate funds.

Charts.css
That's not close to the same complexity, is it?
With the HTML + CSS solution, all my program has to produce is a HTML table. Very easy.
With SVG my program has to create not just a data table, but the custom SVG code to paint the actual charts. I'm actually doing that on pc-kombo, https://www.pc-kombo.com/us/benchmark/games/cpu/compare?ids%... shows it, the image is SVG. But it's created with https://github.com/DannyBen/victor/, so my ruby code has to describe all the details of that image, including manually saying how each bar chart should look. Even with the awesome victor library that wasn't all that easy.
Alternative is a JS library that produces the SVG code, but then it's exactly as complicated as with regular JS libraries, it just changes the output.

Namespaced errors for Ruby
A naive implementation - there's just one custom error and most of the API relies on built-in errors like RuntimeError and ArgumentError. Needless to say, this is a poor showing, problems will be hard to debug.
