Training Hiring Managers to Interview Effectively (and Improve Hiring Decisions)

One of the biggest challenges organisations face in recruitment is not attracting candidates — it’s making the right hiring decisions. Training Hiring Managers to interview is often overlooked, yet it has one of the greatest impacts on hiring quality.

In most organisations, hiring managers are responsible for interviewing and selecting candidates, yet many have never received formal training. They are simply expected to “know how.” The result? Inconsistent interviews, poor questioning, unconscious bias, and ultimately, poor hiring outcomes.

The Risk of Untrained Interviewers

1. Interviews are often unstructured and inconsistent

Without training Hiring Managers to interview effectively, interviews tend to vary significantly between managers, teams and departments, even from interview to interview for the same position. Questions differ, evaluation criteria are unclear, and decisions are often based on “gut feel” rather than evidence based. An unstructured interview can mean candidates are being scored against different criteria, no core competencies or capability has been identified. The candidate can also have a poor experience too (think rambling managers or poor questions and no sell on the role or organisation).

Unstructured (“bar stool”) interviews lead to:

• Inconsistent hiring decisions
• Difficulty comparing candidates
• Increased risk of making poor hires

2. Poor interviewing leads to poor hiring outcomes

The quality of your interview process directly impacts:

• Quality of hire
• Employee performance
• Retention
• Team dynamics

When interviews are unstructured, organisations are more likely to hire based on likeability rather than capability. This means outgoing candidates who can “sell” themselves tend to do well, against introverts or those who may have better experience and or capability fit. Having a good structure to the interview (plan) with structured questions coupled with good probing techniques are key to uncover real evidence of competence per candidate. Plus means all candidates are treated equally.

3. Increased risk of bias and compliance issues

Untrained interviewers are more likely to:

• Ask inconsistent or inappropriate questions
• Introduce unconscious bias into decisions
• Fail to document decisions properly

This ultimately increases exposure to:

• Discrimination risks
• Compliance issues
• Reputational damage

What Effective Interview Training Should Include

Training Hiring Managers to Interview effectively goes beyond “tips and tricks”- it builds structured capability across the entire interview process.

1. Defining Role Requirements and Success Criteria

Before interviewing begins, hiring managers must be clear on:

• What success looks like in the role
• The key competencies required for the position
• What differentiates an average vs high performer for this position

Without this clarity, interviews and questions can lack focus and consistency.

2. Structured Interview Frameworks

Training should introduce structured interview approaches, including:

• A structure interview format – such as our WIGGS model (Welcome, Introduction, Gaining Information, Giving Information, Sales and Closing).
• How to write Competency-based interview questions (e.g. “Tell me about a time…”)
• Why we use Competency-base questioning as a technique
• Question preparation - Consistent questions for all candidates
• Why unstructured interviews can fail

Multiple research studies have shown structured interviews are proven to be more reliable and effective than informal “bar stool” conversations.

3. Question Design and Probing Techniques

Hiring managers need to learn how to:

• Understanding the difference between question types: Open, Closed, Leading, Hypothetical questions and why and when to use them.
• Ask open, relevant, competency based and targeted questions
• Probe in depth for real, specific evidence (the STAR technique)
• Avoid leading or biased questions

This ensures interview questions and responses are meaningful and comparable across all interviews and fair for all candidates. Plus, it ensures we get the best out of each candidate at every interview in the fairest possible way, reducing bias.

4. Notetaking and Observation Skills

One of the most overlooked areas of interview skills training is:

• How to observe candidate responses
• How to document evidence objectively
• How to separate fact from fiction and interpretation
• Good note-taking skills - improves both decision making quality and compliance.

5. Candidate Evaluation and Decision-Making

Effective training also includes:

• Using structured scorecards
• Assessing candidates against defined criteria (Scoring systems)
• Making evidence-based decisions

This reduces reliance on intuition, less reliance on “gut feel” and improves consistency of hiring practices across all hiring managers and departments.

6. Reducing Bias in Interviews

Training should include and help hiring managers:

• Recognise common forms of unconscious bias in recruitment
• Apply consistent evaluation frameworks for each candidate
• Focus on capability rather than similarity (affinity bias)
• Recognising bias in others or one’s self and how to adjust processes to eliminate these risks

Reducing bias leads to fairer, more inclusive hiring outcomes.

7. Understanding Legal and Compliance Requirements

Hiring managers should understand:

• What questions can and cannot be asked at interview
• Discrimination Acts for their State and at a Federal level (Australian law)
• The difference between Direct and indirect Discrimination and where this may play out in recruitment
• Other Equal Employment Opportunity (EEO) considerations
• The importance of fair and consistent processes
• Other legal matters such as the Privacy Act, Ethics and Code of Conduct, WH&S rules that may impact a hire e.g. age for certain roles

This reduces organisational risk and supports compliant hiring practices.

What Good Interviewing Looks Like in Practice

When hiring managers are trained effectively, interviews become:

• Structured and consistent across candidates
• Focused on competencies and role requirements
• Evidence-based rather than opinion-based
• Fair, inclusive, and compliant
• Efficient and easier to evaluate
• Recorded outcomes with good notes and scores

This leads to more confident hiring decisions and better outcomes. Plus an audit trail if the hiring process is ever questioned.

Common Mistakes Untrained Hiring Managers Make

We observe without training, hiring managers often:

• Rely on informal or conversational “chats” at interviews
• Ask inconsistent or irrelevant questions
• Ask inappropriate questions
• Focus on “liking” the candidate rather than their capability to do the role
• Fail to probe for real evidence of competence and capability
• Make decisions without structured evaluation or scoring
• Fail to make notes or document the process
• Struggle to justify decisions as to why one candidate was stronger

These issues are common - but they are also highly fixable with the right skills training.

How to Implement Interview Training in Your Organisation

Step 1 – Assess current capability

Understand:

• How interviews are currently conducted
• Where inconsistencies or risks exist
• Which managers require more support

Step 2 – Provide structured training

Deliver practical, applied recruitment skills training that includes:

• Real scenarios
• Practical tips and tools
• Structure questions and interview format development
• Interview practice
• Tools and frameworks
• Knowledge of EEO and the law
• Know the process including offer stage, ref checking and onboarding

Step 3 – Embed tools and processes

Training must be supported by:

• Interview guides
• Scorecards and rubrics
• Competency framework
• Standardised templates
• A potential question bank
• EVP and Employer Branding messaging to share with candidates

Step 4 – Reinforce and review

Capability improves when:

• Training is reinforced
• Every hiring manager is trained (regardless of level – yes, even GM’s).
• Fairness and consistency can be observed
• Processes are reviewed
• Feedback is provided
• Those new to leadership are also trained (ongoing access to training).

The Link Between Interview Training and Recruitment Performance

Training hiring managers to interview effectively is not just about improving interviews, it’s about improving overall recruitment performance.

Organisations that invest in this capability typically see:

• Better quality hires
• Improved hiring decisions
• Improved candidate experience
• Faster decision-making to hire
• Reduced hiring risk
• Improved consistency across teams
• Stronger alignment to workforce needs, culture and behaviours
• Better engagement in the process from internal staff and perceived fairness
• More D&I considerations applied throughout the process
• Reduced turnover
• Higher hiring manager satisfaction (with the service)
• Clear roles and responsibilities between HR and Managers

Where to Start?

For organisations unsure where their gaps are, starting with a Recruitment Health Check can easily help identify:

• Capability gaps in the process
• Hiring risks
• Capability gaps in interviewing
• Process inconsistencies
• Spend and time issues
• Bottle necks or blockages
• Candidate experience feedback
• Hiring Manager feedback
• Quality issues on current hires

From there, targeted Recruitment Skills Training can be implemented to improve outcomes.

My Final Thoughts and Observations

Hiring is too important to rely on unstructured interviews and intuition. Or just leave it for hiring managers to “work it out”.

Recruitment is a leadership skill set, essential for business strategy and important to get the right competence, culture and behaviours into the organisation and should be left to chance. It ultimately impacts the bottom line.

Training hiring managers to interview effectively is one of the most practical and impactful ways to improve recruitment  and business outcomes.

It reduces risk, improves decision-making, and builds stronger, more capable teams.
