How to write interview questions to get evidence you need to identify the right person

Along with resumes and application forms and reference checks, interviews are an important component of the process that will assist you to identify the right person to hire—as distinct from the “best” person.

Interviews are an opportunity to learn more about candidates than what you learned from their resumes or application forms. It’s an opportunity to collect evidence about candidates’ previous on-the-job experience. Have they done the right things in the right way for your workplace?

The questions you ask during interviews determine the quality of the information you gather. Before writing your questions, be clear about what you want to learn from the candidates’ answers.

Questions should be tailored to the vacancy to be filled and to the culture of your organization.

If you ask questions because they are the questions that everyone is asking, you can be assured that those are the questions the candidates have prepared themselves to answer. You will learn little about candidates from their well-rehearsed answers. 

There are three considerations when deciding what you will ask about:

Your top performers—What do they do that makes them successful? Write and ask questions that require candidates to describe how they have responded to circumstances similar to what they will experience if hired. Do the candidates provide evidence of having responded as your top performers would respond?

Your organization’s values—What candidates have done previously tells you about their values related to integrity, collaboration, teamwork, customer services, etc. Ask questions to ascertain if the candidates’ past behaviour corresponds to how you would want them to perform. Has what they have done demonstrated that their integrity or commitment to collaboration aligns with that of your organization?

Your organization’s future—What skills, competencies and values are required of staff members who will help carry your organization to its desired future? Use interviews to determine if candidates possess what you will need from them to move your organization forward.

Use the following guidelines when writing interview questions:

Think past tense: Ask about what candidates have done, not what they will do. You want evidence of how they have acted, not speculation about what they might do. Keep in mind the principle of behaviour description interviews (BDI). It states that, “Past performance is the best predictor of future performance.” People tend to respond to situations in the same ways as they responded to similar circumstances in the past. Does what you hear from the candidate align with what you would expect top performers to do and the values of your organization? Begin your requests for information with phrases such as, “Describe a time when …” or “Recall when you were …”

Keep your questions short: Challenge yourself to write questions that could be tweeted, especially back when tweets were limited to just 140 characters. The longer the question, the more likely you are to provide hints about how you want it answered. Candidates will listen to interviewers’ words for hints about what they want to hear. The more talkative interviewers are, the less effective they become.

Be prepared to ask followup questions: Probe to learn more. The more you learn about candidates, the better prepared you are to decide who is the right person to hire. Ask when and where what they describe occurred. Encourage them with “tell me more.” Seek clarification when required. Point out inconsistencies.

Plan how you will assess candidates: Create an assessment tool that consists of a rubric against which you assess candidates. In this way, you will be prepared to compare candidates against standards you established prior to the interview and not to each other.

Prepare to take notes: Create a note-taking form that includes your initial request for information, followup questions and the assessment rubric.
