Our interview process used to look like this:
1) Initial 15 minute phone call, 'the basics'. Did the candidate research the business? Are they aligned with what we're looking for? Some basic information about their experience.
3) Tech test/challenge. Takes anywhere from 2 - 8 hours depending on the candidate. Full stack JS - front/backend test.
4) Final interview to talk through the test/candidates code and next steps.
A month or so ago a colleague of mine suggested adding a new step in our interview process. His suggestion was to add a pair coding exercise in the early stages that was relatively short, but would help us identify if a candidate had the following qualities:
- Ability to think on the spot
- Communication skills and ability to talk through their code with others
- Logical thought processes
I introduced a coding challenge designed to be completed in 15 - 30 minutes. The scaffold of the app would be provided for you. You'd have a set of requirements and off you'd go. It was coupled with the initial 15 minute phone call.
The technical challenge? It had to be remote. We didn't want to waste anyone's time if they were the wrong fit. We ended up using VSCode and a live collaboration plugin alongside ngrok which allowed me to share my local development server to candidates over the internet.
It worked surprisingly well. The feedback I've had has been excellent and the challenge I was told, was fun. The lesson to be learned is that you can provide small, fun challenges that give some serious benefit.
I've published the challenge to GitHub. I've also added a new one to the same repo. The plan is to build more and more over time. I'm super open to feedback/suggestions/ideas! Reach out! Each one has a difficulty level, time to complete and a set of requirements.
