Follow up Questions
Do you have any experience with marketing software? Marketing automation? Please explain.
Have you worked with social media? Have you used social media to promote yourself in any way? Please explain.
Take a look at the Rappid.js framework. We have a drag and drop builder built with this framework. Do you think you would have any problems understanding code written with this framework? Bug fixing it? Modifying it? Improving it?
Docker Test
Our dev container uses Alpine LInux image to keep the container size small. We use the same container in production and development. Our feature tests rely on Capybara, and ideally Chrome. But, installing Chrome has been a problem. So, the task was to either 1) get Chrome working, or 2) move to another small image type (like maybe phusion) with the same type setup we have (minimal container, but all the proprietary libraries we need in the image).
Docker Compose Test
Build a docker compose file that, on launch, will start a postgres database, a redis database, and a ruby container, with them linked for networking purposes. Return this as a gist on github back to us.
Regular Expressions
There are two test cases in the linked file. Both of these cases need to pass. Please make it work.
RSpec
Write a simple example of an RSPEC test that loops through a fixture folder, and loads a text file.. in each file, you are checking if you can find the letter “a” in the file. Return this as a gist on github back to us.
Natural Language Processing
Describe how you would solve the problem of finding postal addresses in a plain text file.
Rails
Describe how you would test a modern Rails application? Which tools would you use?
