Debrief Meeting

Directions for Conducting the Debrief Meeting

The Debrief Meeting is an open discussion for the hiring team members to share the information learned during the candidate interviews. Use the questions below to guide the discussion.

Start the meeting by reviewing the requirements for the role and the key competencies and goals to succeed. The meeting leader should strive to create an environment where it is okay to express opinions about the candidate that differ from the consensus or from leadership's opinions.

Scores and interview notes are important data points but should not be the sole factor in making the final decision. Any hiring team member should feel free to change their recommendation as they learn new information and reflect on what they've learned.

Questions to Guide the Debrief Meeting

Does anyone have any questions for the other interviewers about the candidate?

The meeting facilitator should initially present themselves as neutral and try not to sway the conversation before others have a chance to speak up.

Are there any additional comments about the Candidate?

This is an opportunity for all the interviewers to share anything they learned that is important for the other interviewers to know.

Is there anything further we need to investigate before making a decision?

Based on this discussion, you may decide to probe further on certain issues with the candidate or explore specific issues in the reference calls.

Has anyone changed their hire/no-hire recommendation?

This is an opportunity for the interviewers to change their recommendation from the new information they learned in this meeting.

If the consensus is no hire, should the candidate be considered for other roles? If so, what roles?

Discuss whether engaging with the candidate about a different role would be worthwhile.

What are the next steps?

If there is no consensus, follow the process for that situation (e.g., it is the hiring manager's decision). Further investigation may be needed before making the decision. If there is a consensus on hiring, reference checks could be the next step.

Reference Checks

Directions for Conducting Reference Checks

Reference checks are a critical final step in the hiring process for QA Engineers. They provide valuable third-party perspective on the candidate's technical skills, work ethic, and collaboration abilities. Approach reference checks as an opportunity to validate what you've learned during interviews and to gain additional insights about the candidate's performance in real work environments.

When conducting reference checks:

Use the same questions for all references to ensure consistency
Focus on verifying the candidate's testing expertise, problem-solving abilities, and teamwork
Listen for specific examples rather than general impressions
Pay attention to hesitations or qualifications in the reference's responses
Take detailed notes to share with the hiring team

These reference check questions can be used for multiple references. Try to speak with at least one direct manager and one colleague who has worked closely with the candidate. If possible, also speak with someone who has been on the receiving end of the candidate's work, such as a developer who worked with their testing.

Questions for Reference Checks

In what capacity did you work with [Candidate], and for how long?

Guidance: Establish the context of the relationship and the reference's ability to speak to the candidate's skills and work style. Listen for the depth and recency of the relationship, as well as the types of projects they worked on together.

How would you describe [Candidate]'s technical testing skills? What were their particular strengths and areas for improvement?

Guidance: Look for specific examples of technical capabilities rather than general statements. Note which technical skills are highlighted and whether they align with your needs. Pay attention to any mentioned weaknesses and consider whether they would be significant in your environment.

Can you describe a complex testing challenge that [Candidate] faced and how they handled it?

Guidance: This question helps verify the candidate's problem-solving abilities and technical approach. Listen for details about the complexity of the problem, the candidate's methodology, and the outcome. Note how the reference describes the candidate's thought process and determination.

How effective was [Candidate] at communicating testing issues to developers and other stakeholders?

Guidance: Communication is critical for QA Engineers. Note examples of how the candidate documented bugs, explained technical issues to non-technical team members, or navigated difficult conversations about quality. Pay attention to whether the reference mentions any communication challenges.

How did [Candidate] handle situations where there was pressure to release something quickly despite quality concerns?

Guidance: This question helps assess the candidate's judgment, assertiveness, and ability to balance quality standards with business demands. Listen for examples of how they navigated these tensions and whether they were able to maintain appropriate quality standards while being reasonable about business needs.

How would you describe [Candidate]'s approach to test automation and process improvement?

Guidance: Look for insights into the candidate's innovation, initiative, and long-term thinking. Note specific examples of processes they improved or automation they implemented. Consider whether their approach would align with your team's goals and culture.

On a scale of 1-10, how likely would you be to hire [Candidate] again, and why?

Guidance: This direct question often elicits candid feedback. Pay attention not just to the number but to the explanation behind it. A score of 9-10 with specific positive examples is a strong indicator. If the score is lower, probe gently for the specific concerns that prevented a higher rating.

Frequently Asked Questions

How should I prepare my team to use this interview guide effectively?

Share the guide with all interviewers at least 24-48 hours before interviews begin. Consider holding a preparation meeting to review the guide, discuss the role requirements, and assign specific areas of focus to each interviewer. This ensures comprehensive coverage without redundant questioning and helps maintain consistency across all candidate evaluations.

What if a candidate has strong automation skills but limited experience with our specific tech stack?

Focus on transferable skills and the candidate's ability to learn. Strong foundation in automation principles and experience with similar technologies often translates well across different tools. Ask about their approach to learning new technologies and specific examples of when they've successfully adapted to new tools in the past. You can learn more about hiring for potential on our blog.

How should we evaluate candidates with more development experience who are transitioning into QA?

These candidates often bring valuable perspective on software development that can enhance their testing approach. Focus on their understanding of quality principles, attention to detail, and why they're interested in QA specifically. Their coding skills can be particularly valuable for test automation, but ensure they also appreciate the distinct mindset required for effective testing versus development.

What's the best way to assess a candidate's ability to balance thoroughness with time constraints?

The work sample exercise is particularly valuable for this. Observe how candidates prioritize their testing efforts when they can't test everything, what risks they identify, and how they make decisions about test coverage. In behavioral questions, listen for examples of how they've made similar trade-offs in previous roles and the reasoning behind their decisions.

How can we ensure our interview process doesn't exclude candidates from diverse backgrounds?

Review your interview questions to eliminate unintentional bias, focus on skills and capabilities rather than specific experience, and ensure your panel includes diverse interviewers. Consider how to make reasonable accommodations for candidates who might need them. The structured nature of this guide helps ensure all candidates are evaluated on the same criteria, which is one way to reduce bias in the hiring process.

Should we focus more on manual or automated testing skills for our QA Engineer hire?

The balance depends on your specific needs, but most modern QA roles require both skill sets. A good QA Engineer should understand when manual testing is appropriate and when automation would be more efficient. The interview guide addresses both areas, but you can adjust the emphasis based on your team's current capabilities and future direction.
