Interviewing is the most outcome-defining point in the hiring process. High-performing interviewers are your company’s frontline defense against hiring the wrong people, but they must also double as the face of your company and ensure that exceptional candidates leave their interviews impressed. Put simply, interviewers determine whether an organization will succeed in identifying and attracting the right people.

Especially at a time when making every hire count matters more than ever, a high-quality interviewing process is a must-have. So how can you be sure that your interviewers are performing at their peak? How can every hire your company makes improve the average? How can your interviewers be trained such that they are truly capable of intentionally identifying and attracting talent?

What to aim for 📈

Effective interviewers are calibrated with the organization’s values, provide in-depth and targeted feedback on candidates, ask questions that test the limits of a candidate’s knowledge, and are aware of the risks of their unconscious biases.

Ineffective interviewers fail to ask appropriate questions, provide weak feedback on candidates, make their decision in the first 30 seconds, fail to understand the requirements of the role they’re helping to hire for, and — above all — they make bad decisions as a result. (For more on what makes a good vs. bad interviewer, check out our post on the topic.)

Don’t we all want more of the former, and less of the latter?

How the most successful companies in the world are achieving this 🎉

The best organizations in the world rely on interview shadowing as the primary way to train interviewers to the standard they require, and keep them there.

Amazon have their Bar Raiser program, where all successful candidates need to be vetted by an objective and trusted interviewer — the ‘Bar Raiser’ — before an offer can be extended.

Google have their independent, data-driven hiring committees that move the responsibility for hiring decisions for the whole company to a relative-few highly trusted decision makers based on the information their interviewers have managed to capture from a candidate.

Facebook’s hiring teams have different interviewers trained on specific competencies. They believe in shadowing so strongly they have based their entire interviewer training program exclusively around it.

In all these cases (and more!), a consistent interview shadowing program lays the foundation for creating the population of effective, aligned interviewers that these processes rely on.

Interviewer shadowing allows trainees and current interviewers to learn and improve skills within the environment in which they will actually use them, not a classroom. It enables trainees to receive feedback based on things that actually happened, rather than theoretical feedback on hypothetical situations. It enables the development of interviewing skills uniquely tailored to the organization and the things that matter to you, not undifferentiated skills that are unlikely to attain a competitive advantage in the war for talent.

What is interviewer shadowing? 👥

Shadowing is when the trainee interviewer wishing to improve their interviewing skills observes another talented/respected interviewer conducting an interview.

Reverse Shadowing is when a trainee interviewer conducts an interview, while an experienced interviewer within the company observes. Afterwards, the experienced interviewer provides feedback on how they ran the interview and can also offer a second opinion on the candidate to the hiring committee or decision-maker.

As an example, here’s what our interviewer shadowing program looks like at Metaview: We start interviewer onboarding with virtual shadow paths where trainees listen to a series of hand-picked interview recordings so they can observe real-life examples of strong interviews (we use our own product to do this). Then, we do reverse shadowing where an experienced interviewer reviews a recording of an interview a new trainee has led and spends time thoughtfully commenting on it. Finally, we move into continuous improvement where we monitor consistency and quality metrics across interviews ongoing.

How does interviewer shadowing benefit the organization? 🚀

Getting your interview process right depends on equipping your interviewers with the right resources, training, and knowledge to provide a rigorous, consistent and fair process — every time. Once you have a solid interviewer training process with shadowing in place, you’ll see payoff in 5 key areas:

  • Faster time-to-hire
  • Improved candidate acceptance rate
  • Better quality of hire
  • Reduced bias
  • Increased efficiency

Applying shadowing practices helps everyone involved: trainees, seasoned interviewers, and the organization as a whole. Ultimately, higher quality interviews lead to higher quality hires, which benefits all involved.

Trainee interviewers

  • Engaged Learning: Interviewer training shouldn’t be a box ticking task. Shadowing engages prospective interviewers by tailoring their training to them whilst learning in an interactive environment. Classroom exercises or online tutorials are never as effective as hands on learning.
  • Expert Coaching: Your company has unique values and your interviewers should reflect these. Interviewers get to learn from the best interviewers in your company which calibrates them quickly and efficiently with company values.
  • Fast Track: Shadowing allows you to recognise promising interviewers quickly, so you can have access to your best new interviewers with minimal delay. This then reduces the interview burden on your existing interviewers by more efficiently growing the pool of trained interviewers (as candidate interviews can be spread amongst more trusted interviewers).

Trained Interviewers

  • Motivation: Measuring people on their interviewing skills motivates them to aim to be great at interviewing. Hiring standards will grow organically within your company as people compete in this positive sum game. Without shadowing, people see no opportunities for growth or progression within their interviews so aren’t motivated to improve after their initial training.
  • Continuous improvement: It seems crazy to spend so much on training a key skill only to then never review someones progress. With shadowing every interviewer is always getting better by having their interviews assessed and assessing others. This means the bar for hiring at your company is always being raised and every new interviewer is trained to the standard of your best interviewers.

The organization:

  • Confidence: You can be confident that hiring standards across the company are held to a consistently high bar. This results in a high-level of trust among colleagues that each person has earned their place. With one-off training methods interviewers can go for years without any kind of review of their practices, and poor interviewing only becomes apparent when it is too late (when you’ve made too many bad hires!). Interviewer shadowing ensures the bar for quality is constantly upheld.
  • Cross functional alignment: Shadowing encourages collaboration across teams in your company and aligns their hiring standards, so you can employ a consistently high-quality process that reliably identifies and attracts top talent.

Conclusion 🏁

Interview shadowing is by far the most effective way to train your interviewers. The best companies in the world use it to gain advantages in the war for talent and avoid costly mis-hires.
