What to expect from a take home coding challenge ♂
Hi all and sorry for responding so late. I was hoping to respond once I heard back from the employer but I don’t think I’ll hear back till about Wednesday. The challenge required me to add a component to the employer’s website and to also make another component more accessible to visually impaired users. By components, I also mean pages.
The employer, let’s call them “ABC”, hosts a number of medically related websites and I was required to update two pages, or components. In my first challenge I added an image carousel feature to the website (no bootstrap, just vanilla JS with no libraries or shortcuts) so I had to add code to the js, html, styl (they use this for css), and also add a markdown file with reasoning and explanation, etc. As far as the accessibility component goes, the first thing I did was to add alt tags to all images, and I added, essentially a walkthrough based on information I read on the WAI site and some other resources. The walkthrough would guide engineers on best practices when approaching the building of visually accessible web pages and standards.
Adding the components was actually not too bad, it was getting the environment to work and play friendly while I worked on the components that was a bit of a pain. I had to update my local host files so that the style guide hostnames would work while I’m hosting locally (127.0.0.1), after setting up a Docker container. That was the next challenge: setting the Docker container up to pull and host ABC’s WordPress pages. It was only a matter of three command line commands, but I think ABC intentionally gave me cloudy directions that weren’t exactly clear to see if I could figure out how to get around some issues and get the container set up and working. Then, I just had to get Apache running with a simple command. I never used WordPress, Docker or ran Apache directly so I had to learn how to do this on the fly.
It was fairly easy to replicate the environment once I got it up and running, but again, the instructions were sketchy, at best so I had to work around this and ask ABC for clarification. Part of it, I felt, was that they were testing me to see how I would communicate with them and how clearly I could walk through what I had already done in order to figure out what else I needed to do to get the environment running and get the builds to jive once I starting adding components, updating and seeing my work.
