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 for success as a Frontend Developer.

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.

Question: Has anyone changed their hire/no-hire recommendation?

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

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

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

Question: What are the next steps?

Guidance: 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 our hiring process for Frontend Developers. They provide valuable third-party insights into the candidate's past performance, technical abilities, collaboration skills, and work style that may not be fully revealed during interviews.

Approach reference checks as a fact-finding mission, not just a box-checking exercise. The goal is to gather specific examples and context about how the candidate has performed in real work environments. These conversations can validate our impressions from interviews or reveal new information that may influence our final decision.

Best practices for reference checks:

Request that the candidate make the initial introduction to their references
Conduct multiple reference checks, ideally including direct managers and peers
Prepare your questions in advance but allow for natural conversation
Listen for hesitations, tone changes, or qualified answers that may signal concerns
Ask follow-up questions to get specific examples rather than general impressions
Take detailed notes during the conversation
Consider the relationship between the reference and candidate when evaluating responses

Questions for Reference Checks

How do you know [Candidate Name], and what was your working relationship?

Guidance: Establish the context of the relationship, including reporting structure, duration of working together, and how closely they collaborated. This helps frame the rest of the responses.

What were [Candidate Name]'s primary responsibilities in their role?

Guidance: Compare the candidate's description of their role with the reference's account. Look for alignment on the scope and nature of their work.

Can you describe a significant frontend development project the candidate worked on and their specific contributions?

Guidance: Listen for details about technical skills, problem-solving approach, and impact. Note whether the reference can provide specific examples or speaks in generalities.

How would you rate [Candidate Name]'s technical skills compared to other frontend developers you've worked with?

Guidance: Ask for examples that illustrate their technical capabilities. Listen for specific technologies mentioned and level of proficiency described.

How effectively did [Candidate Name] collaborate with others, such as designers, product managers, and other developers?

Guidance: Look for specific examples of cross-functional collaboration. Note any mention of communication style, flexibility, and how they handle differing opinions.

What areas of improvement or development would you suggest for [Candidate Name]?

Guidance: Everyone has areas for growth. A reference who can't identify any may not be providing a complete picture. Listen for how the candidate responds to feedback and their willingness to learn.

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

Guidance: This direct question often reveals the reference's true assessment. Ask for specifics that justify their rating, especially if it's particularly high or low.

Frequently Asked Questions

How should I prepare for interviewing a Frontend Developer candidate?

Before the interview, review the job description and this guide thoroughly. Familiarize yourself with the candidate's resume, portfolio, and any work samples they've provided. Prepare your environment for any technical demonstrations or coding exercises. If you're conducting the technical assessment or deep dive, refresh your knowledge on current frontend technologies and best practices. Our guide on conducting job interviews offers additional preparation tips.

What if the candidate has strong technical skills but seems to lack communication abilities?

Consider the specific requirements of your team and project. Frontend developers interact regularly with designers, product managers, and other developers, so communication is important. Evaluate whether the communication gaps could be improved with mentoring or if they would significantly hinder collaboration. Look at their problem-solving abilities and willingness to learn as potential indicators of growth potential. Balance technical excellence with team fit based on your specific needs.

How should I evaluate a candidate's portfolio or previous work?

When reviewing portfolios, look beyond visual appeal to assess code quality, project complexity, and problem-solving approach. Ask candidates to explain their decision-making process and contribution to specific projects. Consider whether their experience aligns with your technology stack and project requirements. Remember that portfolios might show polished final products but not reveal the development process, so use the interview to explore their approach and capabilities further.

What should I do if a candidate performs poorly on the technical assessment but has impressive experience?

Interview performance isn't always indicative of on-the-job performance. Consider factors that might have affected their performance, such as nervousness or unfamiliarity with the specific problem. If their experience is strong, you might want to give them another opportunity with a different format or problem. You can also focus more on their past work accomplishments and reference checks to get a more complete picture of their capabilities.

How can I assess if a candidate will be able to grow with our technology stack?

Look for signs of learning agility and adaptability rather than specific technology experience. Ask about times they've had to learn new technologies quickly or adapt to changing requirements. Candidates who demonstrate curiosity, self-directed learning, and the ability to apply concepts across different technologies often adapt well to new stacks. Their approach to problem-solving and fundamental understanding of frontend principles are usually more important than specific framework experience.
