A/B Test Asynchronous Interview Questions Predictive Validity: A Comprehensive Study

In today's competitive job market, companies are constantly looking for ways to improve their hiring process and select the best candidates for the job. One method that has gained popularity in recent years is the use of asynchronous video interviews, where candidates record their responses to pre-recorded questions at their own convenience. This method allows for a more efficient and flexible screening process, but how accurate and predictive are these asynchronous interview questions?

This is where the concept of A/B testing comes into play. A/B testing is a method of comparing two versions of a product or process to determine which one performs better. In the context of hiring, it involves comparing different types of interview questions to assess their predictive validity in terms of job performance and turnover. In this article, we will delve into the key insights and findings of a comprehensive study on A/B testing asynchronous interview questions' predictive validity.

The Study

The study, titled "Responses to Past-Behavior Questions in Face-To-Face and Asynchronous Video Interviews: Storytelling, Interview Performance and Criterion-Related Validity" was conducted by researchers from the University of Guelph and University of Calgary. The study aimed to compare the effectiveness of four different types of interview questions in predicting job performance and turnover:

1. Past behavioral questions
2. Background questions
3. Job knowledge questions
4. Future-oriented questions

The researchers collected data from over 500 participants who were applying for a variety of positions in a large Canadian organization. The participants were randomly assigned to either a face-to-face interview or an asynchronous video interview. The interviews consisted of a mix of the four types of questions mentioned above.

Key Findings

The study revealed that past behavioral and background questions significantly predicted job performance and turnover, while job knowledge and future-oriented questions did not. In fact, past behavioral questions had the highest predictive validity, followed by background questions. This highlights the importance of asking candidates about their past experiences and behaviors in the workplace.

The researchers also found that asynchronous video interviews yielded similar results to face-to-face interviews in terms of predictive validity. This suggests that asynchronous interviews could be a viable alternative to traditional face-to-face interviews, especially in situations where in-person interviews are not feasible.

Additionally, the study found that storytelling played a crucial role in the effectiveness of past behavioral questions. Candidates who used storytelling in their responses were rated higher in terms of interview performance and had a lower likelihood of turnover. This emphasizes the importance of not only asking the right questions but also encouraging candidates to provide detailed and specific responses.

Implications for Practice

The findings of this study have several implications for hiring practices. Firstly, it highlights the importance of using past behavioral and background questions in interviews to assess a candidate's potential job performance and likelihood of turnover. These types of questions allow for a deeper understanding of a candidate's past experiences and behaviors, giving employers insight into how they may perform in the future.

Secondly, the study suggests that asynchronous video interviews can be a valuable tool in the hiring process, especially in situations where face-to-face interviews are not possible. This method allows for a more convenient and flexible screening process, without sacrificing predictive validity.

Finally, the study emphasizes the importance of storytelling in interview responses. Encouraging candidates to provide detailed and specific examples of past experiences can give employers a better understanding of their skills and abilities, and ultimately, their potential for job performance.

Conclusion

In conclusion, the study on A/B testing asynchronous interview questions' predictive validity provides valuable insights into the effectiveness of different types of interview questions in predicting job performance and turnover. It highlights the importance of using past behavioral and background questions, as well as the potential benefits of using asynchronous video interviews in the hiring process. Employers can use these findings to improve their hiring practices and select the best candidates for the job.

If you are looking to improve your hiring process, consider incorporating past behavioral and background questions into your interviews, and explore the use of asynchronous video interviews. By doing so, you may increase the predictive validity of your interviews and ultimately, select the best candidates for your organization.
