What is a Candidate Assessment Tool (and Why Get One)?

A candidate assessment tool is software designed to evaluate job applicants based on various criteria, such as soft skills, hard skills, personality traits, and cultural fit.

These tools streamline hiring processes by automating pre-employment checks, typically with online skills tests, personality tests, and situational judgment assessments.

They help hiring managers make more informed decisions about which applicants to interview and ultimately hire.

The key outcomes are:

• Reduced time-to-hire for large workforces
• Standardized, fair evaluation processes
• A stronger team packed with high-quality talent

All candidate assessment tools have their own capabilities and credentials. The right one for any business depends on its objectives.

For example, if a company hires for a wide range of roles in a niche industry, tools with lots of tweakable assessment templates will work best. If a company hires in high volumes for a few specialized roles, tools with customizable assessment scoring and pass thresholds work best. Out-of-the-box self-serve software could be more suitable for a hiring manager at a small business.

Here's a run-down of tools to help you understand the landscape and make an informed decision.

A word on pricing: Recruitment assessment tools are advanced pieces of software. Rather than publish rigid pricing structures, most providers—including HiringBranch—tailor their plans to companies’ precise needs. Contact their experts to discuss your challenges and get accurate quotes.

HiringBranch is a conversational communication and soft skills hiring assessment, offering proven advantages over traditional multiple-choice and standardized language tests.

Rather than relying on rigid templates, HiringBranch uses conversational AI with assessment content tailored to specific roles and industries. Using open-ended questions, the AI evaluates not just what candidates say, but how they say it.

The result?

User-friendly for employers and candidates, HiringBranch has replaced millions of manual assessments and psychometric tests for high-volume hiring teams in telecommunications, retail, health, banking and insurance, IT, and more.

Here’s how the talent team at IT services and consulting firm Infosys described their experience of using HiringBranch:

"HiringBranch has made hiring easier and faster by screening a huge number of candidates automatically. HR used to sit in 15-20 minute interviews consuming a huge amount of time. That time is cut by 80% now."

• Better hiring performance guaranteed
• The People Skills Framework helps you assess your current workforce and future requirements
• AI open-ended ‘job preview’ question format that is 4X more reliable than multiple choice

Ways to Optimize Candidate Assessment Software ROI

1. Define Clear Objectives

When a hiring team is clear on what it wants to achieve by implementing candidate evaluation software, it can confidently choose a tool with useful features and capabilities.

Employers can also use objectives to measure their implementation’s success. For example, if the primary goal is to speed up recruitment, the team can track a metric like time-to-hire after onboarding.

Other common hiring objectives include increasing workforce diversity, standardizing skill proficiency, and raising the quality of hire.

2. Monitor Candidates to Prevent Cheating

Anti-cheating measures like keystroke analysis, video recordings, and plagiarism detection deter and uncover dishonest behaviour to make assessments more reliable. 

That invariably leads to better-informed hiring decisions.

HiringBranch monitors candidates through video face detection to prevent cheating, allowing users to hire on merit.

3. Work Smarter with Artificial Intelligence (but Stay Vigilant)

AI algorithms can analyze large volumes of candidate data quickly and accurately, providing valuable insights into candidates’ skills, likely job performance, and suitability. That means employee assessment tools with genuine AI capabilities let users work more efficiently while eliminating human error at various stages of the hiring process. Using AI can lead to near-perfect selection accuracy, reducing bad hire rates and time-to-hire. No wonder Workable found that almost two-thirds of HR professionals used AI for hiring in 2023.

Just be wary of false AI promises. Some tools that claim to be “AI-generated” or “AI-infused” often only use automation. Others, like HiringBranch, leverage AI in natural language processing, speech, skills recognition, and more to evaluate candidates’ responses to questions or instructions. 

It’s also vital to understand where a tool’s AI training data comes from, and whether it could be biased. Another tip is to check if you’re required to train the AI yourself or if the vendor does it for you. 

To avoid AI 'marketing' traps, ask vendors for AI validity documentation. Or even better—because what layman can read AI documentation?—ask for an AI third-party auditor report that validates governance and biases for you.

4. Integrate with Other Tools

Integrating candidate assessment software with other HR and business tools lets users synchronize data across different stages of the recruitment process. This is done using systems like an ATS and human resource information system (HRIS). Users can then enhance candidate and team member profiles with assessment results or better still, skills level data.

Depending on its chosen software, the hiring team may also be able to integrate project management apps, email clients, and video interviewing tools.

5. Gather Feedback from Team Members and Candidates

Collecting feedback from internal stakeholders lets recruiters assess the usability and effectiveness of their candidate assessment software.

By exploring stakeholders’ experiences and pain points, employers can find opportunities for improvement and ensure everyone is using the tool effectively.

Getting input from candidates who’ve gone through the assessment process is helpful too. Addressing any issues they raise helps hiring teams maximize engagement for future users.

Dig even deeper by testing tools side-by-side. Put yourself in the candidates’ shoes, take an example test and see what you prefer. If a multiple-choice format hinders your experience, it’ll likely affect applicants in the same way.  
‍

Final Thoughts

Adding a skills test to the hiring process filters out poor-fit hires to save companies time and strengthen their workforces faster.

The right candidate assessment tool will make that evaluation process a breeze so recruiters can focus on more important tasks, like sourcing and interviewing a talent pool’s top candidates before the competition has a chance.

Many tools offer more than just assessments and some businesses will find extra features helpful. But don’t let bells and whistles distract you from your hiring goals. For example, customizable tests are only useful if you have the time and talent to craft quality, unbiased questions. And AI is only valuable if it tangibly improves the evaluation process.

Ultimately, hyper-focused, specialized tools built for your type of recruitment will inevitably deliver better outcomes—now it’s time to put some to the test.
