Привет. У меня спрашивали в основном все что спрашивают везде. Единственное было два сложных вопроса:
1. Описать все что происходит когда грузится страница в браузере. Типа от отправляется запрос на dns, после его обрабатывает веб сервер и тд уже в рельсу
2. Если вдруг появится репорт что медленно работает фронт, то с чего начну деббагинг
Знание React ( работал или нет )
Lambda , proc, block

How to Run a Rails App in Production Locally
  1. Add gem 'rails_12factor' to your Gemfile. This will add error logging and the ability for your app to serve static assets.
  2. bundle
  3. Run RAILS_ENV=production rake db:create db:migrate db:seed
  4. Run rake secret and copy the output
  5. From the command line: export SECRET_KEY_BASE=output-of-rake-secret
  6. To precompile your assets, run rake assets:precompile. This will create a folder public/assets that contains all of your assets.
  7. Run RAILS_ENV=production rails s and you should see your app.

Remember to clobber your assets (rake assets:clobber) and re-precompile (rake assets:precompile) if you make changes.
