The Top 5 Coding Interview Tools to Hire Better Software Engineers in 2024

software engineer vs software developer

Did you know the cost of a wrong engineering hire can go up to 3x their annual salary?

That’s because costs go beyond repeating the recruitment process. A bad hire could impact team morale, reduce productivity and even harm your reputation as an employer.

This is why thoroughly evaluating talent during the hiring journey is crucial. In fact, it’s even more critical for remote roles which constitute around 80% of jobs in software engineering.

But how do you recreate the experience of an in-person coding interview online?

In this article, we’ll look at how a coding interview tool can help you achieve this, as well as the top coding interview tools in the market.

Let’s dive right in.

Here’s why a coding interview tool is a good idea for employers

1. Evaluate developers effectively

We can’t start any other way – the main advantage of a coding interview tool stems from the ability to gauge developer skills. 

Everything else we talk about below flows from this. 

During a collaborative interview with a shared code editor, recruiters and hiring managers can follow the candidate’s thought process as they solve a problem in real-time. 

It’s hard to accomplish this as effectively with other methods like take-home projects or assessments as they allow for manipulation and often lack the context behind why a candidate took a certain decision. The best alternative is an on-site interview which is much more expensive and time-consuming for everyone involved.

So, all else being equal, a coding interview tool will help you understand a candidate’s strengths and weaknesses better. 

2. Reduce unconscious bias

Although it’s hard to acknowledge, unconscious biases are common in recruitment and may greatly affect staffing decisions. 

With a coding interview tool, you can gain an extra dose of objectivity free from unhelpful prejudice.

Features like anonymous code playback give hiring managers a clear view of a candidate’s skills without obscuring their decisions. 

So, if you feel like unconscious biases may be harming your team composition, a coding interview platform can help mitigate such problems.

3. Team transparency

While 1:1 interviews are prone to subjective evaluation, a coding interview platform that automatically saves the interview is visible to other team members and the interviewers themselves.

This makes it easier to evaluate a candidate collaboratively as a group and improves hiring transparency. You can also go back and look at the interview with a fresh perspective, free from momentary thoughts and feelings. 

4. Faster time to hire

One of the biggest cost factors for any recruitment process is time to hire. 

Not just in terms of monetary costs but also the opportunity cost of making progress faster and the burden on the rest of the team as they wait for a new hire to onboard and start making an impact. 

With a coding interview platform, you can evaluate developers remotely without having to travel or schedule meeting rooms. This makes it easier to hold more interviews and find the right person faster. 

Other features that speed up hiring include:

  • The ability to track and organize interviews in one place
  • Creating interview links with a single click
  • Integration with existing HR tools and systems

Tools like CodeInterview allow you to create an interview link in seconds and share it with a candidate via email or a different channel. 

5. Centralize tech interviews without relying on third-party tools

If you feel like your candidate interviews depend on too many tools like your calendar, video conferencing app and applicant tracking system, a coding interview tool will help you centralize management. 

The ability to have a live call with audio/video in addition to a code editor reduces the need for third-party video conferencing apps like Zoom or MS Teams. 

In addition, you can save all of your pre-set questions and create new templates within a coding interview platform so you don’t need a separate system for this. 

6. Better collaboration between recruiters and hiring managers

With a coding interview tool, you can invite all relevant stakeholders to achieve higher levels of teamwork and collaboration in hiring. 

Instead of creating and maintaining new channels of communication for each candidate, your coding interview schedule and history are saved in one place and available for everyone involved to review at any time. 

In turn, this makes communication and decision-making between recruiters and hiring managers better due to easier access to interview data.

7. Easier remote hiring

As more and more companies embrace a remote or hybrid working model, hiring off-site at scale will be more important. 

With a coding interview tool, you can make the transition easier and digitize, at least partially, your tech hiring process. 

When you or candidates don’t have to travel for interviews, you can expand your talent pool beyond local geographies while saving time and money organizing in-person meetings. 

How to avoid creating a bad experience

When choosing a coding interview tool, there are several risk factors related to the candidate experience and internal usage: 

Prioritize ease of use
You need a tool that’s intuitive for candidates with little or no experience using it. So look for an option with a familiar code editor interface. 

Minimize process interference
There is a thin line between process improvement and harm when implementing a new tool. Look for a solution that’s easy to integrate with your existing setup and does not cause a big shift in organizational habits. 

Ask the right questions
There is a general sentiment, especially among senior developers, that tech interviews are designed to expose their weaknesses. One of the senior developers, for better interviews, that customers do not suffer from asthma and that there are no weak points, then on this website you can buy generic Ventolin. Asking theoretical questions with extremely rare practical applications may push talented engineers away, despite having tons of relevant experience.
