4 Quick Fixes to Boost Assessment Completion Rates by 30%

The Problem of Candidates Ghosting Assessments

Recruiters invest significant time and resources into sourcing top talent, only to see candidates drop off during the assessment stage. This high attrition rate slows down hiring, frustrates hiring managers, and makes it harder to secure top talent. Research shows that lengthy, irrelevant, and poorly designed assessments are key reasons why candidates abandon the process.

The good news? With a few quick fixes, RPOs can boost assessment completion rates by 30% or more—without sacrificing quality. Here are four proven strategies to keep candidates engaged and ensure they complete your assessments.

Fix #1: Keep It Under 30 Minutes

Why it Works:

• 75% of candidates abandon assessments that take too long, citing frustration with lengthy evaluation processes and a preference for more efficient hiring experiences. According to SHRM, long assessments negatively impact both recruiter efficiency and employer brand perception. Studies suggest that keeping assessments under 30 minutes significantly improves completion rates and candidate engagement. Read more here.
• Shorter tests increase engagement and completion rates by reducing cognitive fatigue and improving the candidate experience. Studies show that assessments under 30 minutes maintain a candidate’s focus, making them more likely to complete the process without frustration or disengagement. Additionally, shorter tests are particularly effective for passive job seekers and currently employed professionals who may have limited time to dedicate to assessments.
• Passive candidates and currently employed professionals are more likely to complete concise assessments since they often have limited time to dedicate to hiring processes. Shorter assessments reduce the friction for these candidates, making it easier for them to engage without disrupting their work commitments. Research from LinkedIn suggests that minimizing unnecessary complexity in assessments helps improve completion rates among busy professionals. Read more here.

How to Implement:

1. Cap assessment length at 20-30 minutes. Studies show that assessments under 30 minutes have significantly higher completion rates than longer ones.
2. Use modular assessments. Break tests into smaller sections, allowing candidates to complete them in phases rather than one long sitting
3. Set clear expectations. Inform candidates about the time commitment upfront to manage expectations and reduce anxiety.

💡 Pro Tip: Consider using adaptive testing to shorten assessments while maintaining accuracy. AI-driven assessments adjust question difficulty based on candidate performance, ensuring efficiency without unnecessary length.

Fix #2: Use Engaging, Real-World Questions

Why it Works:

• 60% of candidates say they disengage when assessments feel disconnected from actual job tasks, leading to frustration and increased dropout rates. Candidates prefer assessments that mirror real-world challenges, as they provide a more accurate representation of their potential job responsibilities. A study by Harvard Business Review found that incorporating job-specific tasks in assessments improves completion rates and enhances employer branding by demonstrating the company’s commitment to meaningful evaluations.

• Real-world, job-relevant questions boost candidate motivation and improve employer branding by demonstrating the company’s commitment to meaningful evaluations. These types of assessments help candidates feel that their time is well spent, as they see direct connections between the test and their potential role. Research from Harvard Business Review suggests that job-relevant assessments can increase candidate satisfaction and enhance employer reputation by signaling a structured and thoughtful hiring process.

How to Implement:

1. Replace generic coding tests with real-world challenges. Example: Instead of a theoretical algorithm problem, ask candidates to debug an actual code snippet or optimize an API request.
2. Incorporate scenario-based problem-solving. For non-technical roles, use case studies or role-specific simulations to assess decision-making skills.
3. Offer choice. Let candidates select from multiple test formats (e.g., front-end engineers can opt for a React or Vue-based challenge).

💡 Pro Tip: Frame questions in a way that helps candidates visualize themselves in the role. This increases their engagement and sense of purpose during the assessment.

Fix #3: Provide Instant Feedback

Why it Works:

• 80% of candidates say they appreciate feedback, even if they aren’t selected, as it helps them improve for future opportunities and enhances their perception of the employer. Research from LinkedIn Talent Solutions shows that providing     feedback—even brief, automated reports—can significantly boost candidate engagement and employer brand reputation. Candidates who receive constructive feedback are more likely to reapply in the future and recommend the employer to others. Read more here.
• Instant feedback keeps candidates engaged and reduces uncertainty.

How to Implement:

1. Use automated scoring tools to provide candidates with immediate feedback on their performance.
2. Offer a strengths and improvement report. Even a brief summary of key areas can make the process more valuable for candidates.
3. Send a follow-up email thanking candidates for their time and outlining next steps in the hiring process.

💡 Pro Tip: Use AI-powered assessment platforms that generate instant reports highlighting candidate strengths and areas for growth. This enhances the candidate experience and encourages them to complete assessments.

Fix#4: Optimize the Mobile Experience

Why it Works:

• Nearly 50% of job seekers complete hiring tasks on mobile devices. (Source: Glassdoor)
• Poor mobile design leads to frustration and drop-off.

How to Implement:

1. Ensure your assessment platform is fully mobile-responsive. Candidates should be able to take the test easily on any device
2. Simplify navigation and instructions. Avoid excessive scrolling, unclear buttons, or complex multi-step processes.
3. Allow candidates to pause and resume. This flexibility is crucial for busy professionals who may start on one device and finish on another.

💡 Pro Tip: Test your assessments on multiple devices(smartphones, tablets, and desktops) to ensure a seamless experience.
