The 7 Habits of a Highly Effective Interviewer
1 – Determine the Right Interview Methodology
Consider the role you are interviewing for carefully. This will determine the interview methodology suited to identifying the best candidate. Is this a senior executive position critical to the immediate and long-term functioning of the business?
In this instance, both values and competencies will be critical to a successful outcome. As a result, you may wish to adopt a Topgrading methodology, with an interview panel to ensure consistent, unbiased grading of the candidates in terms of cultural and values alignment and experience and competency-based suitability.
However, suppose it is a highly technical "standalone" role within an engineering environment for example. In that case, competency and experience will be of a higher priority than values and cultural fit. In this instance, it is likely that a very focused competency-based interview is more suited to identify the best-fit candidate for the position. A heavily values-based interview may confuse and alienate your ideal candidate in cases like this.
Only once you have identified the correct methodology for the role you wish to recruit, can you set about customising it for your needs.
2- Know Your 'Must-Have' Criteria
Once you have decided upon your methodology, you can begin to identify the skills, qualifications, competencies and values you are looking for in a candidate. This will enable you to compile a list of "must have" criteria for each.
Consider this list very carefully and incorporate each factor into a skills matrix. This will enable you to score each candidate against the criteria in a consistent, unbiased manner.
Once you have established the must have criteria, repeat the process for "nice to have" and "great to have" criteria, for each area relevant to the role.
3- Build Effective Questions
Completing your skills matrix will enable you to create a list of questions tailored to tease out the candidate's abilities against the criteria you are looking for.
Consider your questions carefully. Ensure that they are designed to elicit answers that substantiate the candidate's experience and skills in the area concerned.
For "must have" criteria, you may wish to include the same question in several forms. This will enable you to compare each answer for consistent evidence of the candidate's abilities in that area. Make sure the questions are open-ended and allow the candidate to provide detailed answers.
Consider follow-up questions around subjects of high importance. It may be the candidate possesses the skill set you are looking for but does not fully understand exactly what is being asked of them. Equally, if the candidate is deficient in a "must have" category delving deeper than one question will be vital in determining this.
When considering your questions, it is also important to understand what is and is not permissible under current law. Some links to assist you with this are contained below -

4- Ensure a Consistent Interview Structure
To ensure you appoint the best person for the job, every candidate must be afforded the same opportunity to perform during the interview.
Therefore, you should consider how long you wish each interview to last and structure the meeting in a logical, consistent order that provides each candidate with ample time to answer each question.
Make sure to structure the questions in an objective way, so that all candidates receive the same questions in the same order and have the same opportunity to give a considered, sincere response.
Be sure to take comprehensive notes. It is vital to record information for later reflection and discussion with other stakeholders. Additionally, senior candidates will expect an employer to be organised, credible and thorough. "Winging it" from an interviewer perspective is as damaging as it is from a candidate and may result in your ideal hire taking their talent elsewhere.
5- Apply Consistent and Unbiased Scoring
Inconsistent scoring and unconscious bias can undermine the entire methodology of your interview. If unidentified and not addressed, it can skew outcomes and lead to incorrect hiring decisions, with all the attendant direct and indirect costs to the business.
Consequently, every candidate must be assessed and scored in the same manner, minimising the opportunity for unconscious bias to creep in.
When scoring an Interview, the interviewer should assess the candidate on the must have criteria. As an example, this may be: Performance, Motivation, Potential, Technical Skills, and Cultural Fit.
Each criteria is rated on a scale of 1-5, with 1 being the lowest score and 5 being the highest. Each level will have a suitability against the criteria prescribed, for example-
- Level 1: Unacceptable: The candidate is not qualified to do the job.
- Level 2: Needs Improvement: The candidate has some of the skills required for the job but needs additional development or training.
- Level 3: Competent: The candidate has the required skills and knowledge to do the job.
- Level 4: Very Good: The candidate has the required skills and knowledge and is highly likely to excel in the job.
- Level 5: Exceptional: The candidate is highly qualified, has extensive experience and is exceptionally talented. They are likely to exceed expectations in the job.
The interviewer then adds up the scores for each criteria, to get the overall score for the candidate.
The most consistent way to structure your scoring is against an interview scoring matrix. An example of which can be seen via the attached link. This document also gives examples of a typical interview structure and questions used when selecting a senior executive-
6 - Encourage Questions, Feedback and Summarise
It is essential to build in plenty of opportunities to allow candidates to ask questions about the job and provide honest answers. This will provide valuable additional insight into their suitability for the role or otherwise.
Take notes as the candidate answers questions to build your credibility and enable accurate future reflection. Be sure to ask follow-up questions to gain further insight and test the validity of the candidate's claims.
At the end of the interview, provide the candidate with a summary of the discussion, seek their agreement and understanding and ask if they have any additional questions.
Invite the candidate to provide feedback on the interview process and provide them with an anticipated timeline for when they can expect a decision. This enables you to retain their engagement and positively manage expectations.
7 – Sell The Opportunity Throughout
It is a common misconception at interviews that the candidate must sell themselves whilst the interviewer sits in judgement. Even when the candidate market is strong, be in no doubt that you are competing for the best talent against many other organisations.
Interviews are a two-way process. Candidates assess potential employers as closely if not more so, than the other way round; after all, their entire career may be at stake if they get it wrong.
As such, a highly effective interviewer will be mindful to accurately sell the benefits of the role and organisation throughout the entire lifecycle of the interview process, during the offer stage and whilst managing the candidate's resignation, notice period and onboarding process.
