Choosing the Right Coding Assessment Tool: What to Look For
As a team with 20+ years of experience working with ATS, HR, and assessment platforms to recruit and hire for technical teams, there are a few key factors that we encourage teams to keep in mind when narrowing down the list of prospective coding assessment tools.
Candidate Experience
The hiring process if your first opportunity to leave a good impression on your candidates, and it often sets the tone for how you're viewed as an employer. Sending brainteasers, lengthy multi-day challenges, and confusing or irrelevant questions is just as likely to turn off candidates from moving forward as it is to cause you to hire people who may not be the best fit. You want people who know how to do the job and who see you as the employer they want to work for.
In the best case, you'll want to conduct short, job-relevant interviews or assessments that allow the candidate to feel welcome and at ease in the experience. We have a dedicated guide that walks through constructing the ideal take-home coding challenge.
Beyond the assessment itself, you'll get bonus points if your process includes feedback for the candidate. Why? If a candidate spends time on your assessment and doesn't move forward, your feedback makes a difference in their job search and creates a relationship that could lead to working together down the road. You never know where your paths may converge again in the future!
Real-World Skills
It's not sustainable to hire your team based solely on personality or multi-tasking challenges. Your best candidate is the person who possesses the necessary skills of the job and will rise to meet challenges. You want their on-the-job skills and expertise to shine!
The platform you choose should focus on the real-world tasks that your team carries out every day. Don't hesitate to take the time you need to think through the tasks and what evaluation criteria might look like.
Customization
Think of it like a pizza. Sometimes you want something that’s pre-made, but other times you want to specify what's included and what's left out. Some platforms put customization front-and-center, while others are more prescriptive or may even require reaching out to support to piece solutions together.
Before subscribing to a platform, consider whether you need the option to include your own questions, hiring workflows, branding, or custom-made challenges.
Ease of Setup & Support
How easy is it to get set up and start invite candidates? Ideally, you want a platform that quickly walks you through the process, offers responsive support and onboarding resources, and is user-friendly (for your team and your candidates).
Integration Options
Most platforms on our list integrate with a multiple ATS, recruiting, and HR tools. For the short list of platforms that seem promising to you, check out their website or reach out to their sales team to see if the specific tools you already use can be synced for a seamless experience. Duct-taping solutions together after committing to a platform is always less than ideal.
Scalability
Are you looking to make more hires soon? Do you need to upskill your workforce? Is campus recruiting part of your hiring strategy?
If so, you'll want to pick a platform that takes your workforce goals into account. While some platforms are great for 1:1 invites, others are better at screening and assessing a high volume of candidates. Plus, not every platform offers the option to support your team's skills and development after hiring.
However, it's also important to recognize that sometimes you don't need all those bells and whistles. If you see a platform packed with the features you don't need anytime soon, consider the solution that offers more value in the areas you do need.
That's a wrap! Armed with this list, you now have the full picture of the top coding assessment tools in 2024 and what solutions might be best for your team.
At the end of the day, choosing the right coding assessment platform comes down to your unique needs and requirements. Choose the tool that helps you vet (and empower) top candidates with real-world assessments and make confident hiring decisions.
