hire an interviewer

Hiring the right interviewer is just as important as hiring the right candidate. While companies often focus on attracting talent, they sometimes overlook the quality and effectiveness of the people conducting the interviews. An interviewer’s skill set directly impacts candidate selection accuracy, candidate experience, and ultimately your company’s ability to build a strong workforce.

Recent insights from HRLocker reveal that companies lose up to 20% of candidates due to poor interviewing practices. This attrition not only slows down hiring but can also damage your brand reputation. If you want to reduce bias, accelerate hiring, and enhance your candidate experience, learning how to hire an interviewer who is trained, impartial, and effective is essential.

This guide will take you through why hiring the right interviewer matters, when to bring one in, and practical strategies for finding and selecting the perfect interviewer for your organization. We’ll also introduce modern solutions like Panls.ai Interview-as-a-Service that make this process faster and more efficient than ever before.

Why Hiring the Right Interviewer Matters More Than You Think

Interviewers are the gatekeepers of your talent funnel. Their ability to ask the right questions, recognize skills, and evaluate fit has far-reaching consequences:

  • Avoid Costly Hiring Mistakes: Untrained interviewers often rely on intuition rather than structured assessment, which increases the risk of poor hiring decisions. According to HRLocker, the average cost of a bad hire can be up to 30% of the employee’s first-year salary.

  • Improve Candidate Experience: The interviewer sets the tone for the entire recruitment journey. Professional, respectful, and engaging interviewers leave a positive impression, encouraging candidates to accept offers and recommend your company.

  • Enhance Employer Branding: Each interview reflects your company culture. Skilled interviewers act as brand ambassadors, showcasing your values and work environment.

  • Reduce Time-to-Hire and Increase Retention: Structured interviews conducted by trained interviewers help identify the right candidate faster, reducing hiring cycles and improving long-term retention rates. Tools for interview scheduling and feedback management streamline this process effectively.

  • Limit Bias and Promote Diversity: Awareness and training on unbiased hiring ensure a more inclusive hiring process, attracting diverse talent and fostering innovation.

Investing in the right interviewer is an investment in your company’s future growth and reputation.

When Should You Consider Hiring an Interviewer?

There are specific scenarios when bringing in an expert interviewer can transform your recruitment process:

  • Rapid, High-Volume Hiring: When your company needs to fill many positions quickly, internal teams often get overwhelmed, leading to rushed or inconsistent interviews.

  • Hiring for Specialized Roles: Technical or highly specialized positions require interviewers who understand the role deeply to ask relevant questions and fairly assess expertise. Knowing the nuances of technical assessment and technical recruitment can be crucial here.

  • Remote or Global Recruitment: Interviewers skilled in remote interviewing techniques help navigate challenges related to time zones, cultural differences, and virtual communication tools.

  • Startups and Small Teams Without Dedicated HR: Early-stage companies may not have internal resources or trained interviewers, so external experts can fill the gap.

  • Implementing Fair and Structured Interview Processes: If your organization is moving from informal hiring practices to standardized, bias-free interviews, professional interviewers are invaluable.

  • Onboarding Interviewers for New Teams or Departments: Bringing in experienced interviewers ensures consistent quality and smooth ramp-up when expanding teams.

In these situations, hiring the right interviewer can increase hiring speed, quality, and candidate satisfaction dramatically.
