Coding AssignmentsRecruiting

Need a technical assessment tool, but don’t know which one to choose?

Today, you’ll discover the 30 best coding assessment tools that will help you identify and hire the right candidates and build a world-class technical team.

Want to learn more? Read on!

How to choose your coding assessment tool

First things first:

How do you choose the right tool?

A great developer assessment tool will help you identify the best candidates who are a perfect fit for your team.

That’s why it’s so important that you first choose the right type of assessment tool. Here’s what you need to know.

What type of assessment tool should you choose?

Not all assessment tools are equally good at helping you identify the best tech talent.

Let me explain:

You might know that companies like Google and Facebook are known to use screening questions and whiteboarding challenges in their technical hiring processes.

But using screening tests and tools isn’t the best way to filter your candidates.

In fact, studies show that these challenges are downright bad for technical hiring. People perform worse when they feel stressed and you don’t get a realistic and truthful view of someone’s skills.

In other words:

You might end up hiring the wrong person.

And that can be costly. The cost of a bad hire can be 30% of that person’s first-year salary.

This is why take-home coding assignments are a far better way to assess developer skills. Fortunately, there are some great take-home coding challenge tools out there (which we’ll look at shortly).

Take-home coding challenges let developers perform their tests at home and ideally, in their own development environment.

The idea is to get a good understanding of how developers would perform on the job. This is a completely different assessment approach than asking developers to solve brainteasers. (Which only helps you understand how quick someone is on their feet in stressful situations or how prepared they are for the interview, not their actual coding abilities.)

Ultimately, take-home coding challenges help you hire the best developers. This also means that they help you hire a more diverse team because candidates get to demonstrate their real-life skills and you reduce the risk of biased hiring decisions.

What to look for in a coding assessment tool

So, what should you look for in a coding assessment tool? Good question. Here are the features that are a must-have for well-executed coding challenges:

  • Ease of process. How easy is it to set up and run your coding challenges?
  • Candidate experience. Does the challenge create a great experience for candidates (even those you end up rejecting)?
  • Own challenges. Does the platform let you upload your own challenges?
  • Supported languages/frameworks. How many/which languages and frameworks does the platform support and are these languages/frameworks the ones you need?
  • Number of applicants. How many applicants can go through a challenge? (This usually depends on the subscription level you sign up for, but the tool you choose should make it possible for you to go up to a level where you can assess however many applicants you need.)
  • Number of seats for your team. Does the tool make it easy for your reviewers to review challenges and how many can collaborate simultaneously?
  • Flexibility/customizability. Does the tool make it possible to customize parts of the process according to your needs?
  • Support. What type of support do you get and how fast?
  • Scalability. Is the tool scalable for when your team grows?
  • Plagiarism detection. Does the tool make it possible to detect plagiarism? (However, the tool shouldn’t make this an intimidating experience but instead, effectively weed out plagiarism.)
  • Cost-effectiveness. Does the tool offer more value than what you pay for it?
  • Improved time-to-hire. Does the tool make it faster to hire new developers to your team?

For example, here’s what Aimee, Engineering Mentoring Program Lead, from Babbel said about their hiring criteria before the team started working with us:

It took a lot of research before deciding on a platform to use for administering the Neos code challenges. We obviously had a bit of a unique scenario, thus the main criteria was flexibility, specifically on the below points:

  • Deciding on our own coding challenges
  • The languages the challenges will be available in
  • The number of applicants
  • The number of reviewers from Babbel
  • Pricing

Flexible subscriptionCodeSubmit stood out in all of the above. The feedback that we received from the candidates about their experience was overwhelmingly positive - specifically regarding the ease of the process, as well as the personal and engaging experience the process offered.”

Of course, this depends on YOUR needs and requirements.

For some teams, the defining criterion might be flexibility and for others, that the tool supports the right people on the team (such as non-technical hiring managers).

Start by defining your criteria.

And when you’re done, take a look at the 20 tools here below.

How to use coding assessment tools for the best results

What’s the next step in assessing your candidates after you’ve found the perfect assessment platform for your needs?

You’ll likely want to get started using the platform in the right way and start sending out those invites. But skill assessments don’t always offer the best candidate experience, and developers aren’t that excited about going through hours of unpaid work without anything to show for it (see here and here).

You need a candidate-friendly process for administering assessments.

Avoid poorly executed coding challenges

Coding challenges that are poorly executed will quickly mean that you lose out on talent. But what does a bad coding challenge look like?

Simple: Challenges that are too long (coding challenges that last hours or even days) and have a clunky, anxiety-inducing interface that restricts candidates from performing their best.

And also challenges where the hiring team doesn’t offer any feedback.

Remember: Candidates spend their valuable time on your assignment. Show that you value it too by offering feedback on what they did well and what they can improve the next time around.

Using coding challenges in the right way

What, then, does a good coding challenge look like?

First, start by defining the evaluation criteria. You need to be clear on this before you ask developers to spend time on your challenge.

And second, create a coding challenge that is the right length. Three to four hours is sufficient -- not too long, but long enough for you to have something to evaluate.

Finally, spend some time on making sure that the experience of taking your assessment empowers candidates to demonstrate their skill and do their best work.
