Tailored to the shape of frontend engineer work. Universal questions plus the 3 role-specific ones that surface the most useful signal for this hire.
Universal
How do you know [Candidate] — what was your working relationship?
What you're learning:Establishes context. Their boss has a different read than a peer; a direct report has yet another.
What stood out about [Candidate]'s work?
What you're learning:Lets them lead with strengths. Listen for specifics vs generics — vague answers are a flag.
Where did [Candidate] struggle? Where did they need support?
What you're learning:Every strong candidate has growth edges. A reference who says 'nothing' is a flag of its own.
How did [Candidate] respond when they got hard feedback?
What you're learning:Single best predictor of how they'll perform under stress and how they'll grow in the next role.
Would you hire [Candidate] again, knowing what you know now? For what kind of role?
What you're learning:The crown jewel of any reference check. The 'for what kind of role' qualifier is the truth-tell.
What's the working environment where [Candidate] thrives best?
What you're learning:Cross-check against your team's actual environment. If they need a structured boss and yours is hands-off, big risk.
Is there anything I should be worried about going into this hire?
What you're learning:The open-ended catch-all. Often produces the most useful single fact in the whole call.
Frontend Engineer specific
How well did [Candidate] partner with designers?
What you're learning:Frontend engineers who push back on designs make the product better — IF they do it constructively. Reference will know which side.
How did [Candidate] handle accessibility + performance requirements?
What you're learning:These bite teams 6 months in. References can confirm whether [Candidate] kept them in mind or had to be reminded.
Did [Candidate] propose component-library improvements, or just consume what existed?
What you're learning:Senior FE engineers shape the design system. Mid-level use it. Reference can tell you which level [Candidate] actually operated at.
