How to Choose and Prepare Your Job References

In an era of LinkedIn recommendations and online reviews, it is tempting to treat reference checks as a formality — a box companies check before sending an offer that is already effectively decided. That perception is partially accurate and partially wrong in ways that matter.

For many roles, especially senior ones, reference checks are substantive. Hiring managers and their HR teams ask specific questions about your performance, leadership style, how you handle conflict, and what you would need to succeed in a new environment. A reference who gives a lukewarm or carefully hedged response — even without saying anything explicitly negative — often produces a genuinely damaging outcome. “They were always professional” with nothing more specific is read by experienced interviewers as a reference who cannot endorse enthusiastically.

At the same time, a strong reference — one who speaks specifically and enthusiastically about your performance, who can tell a detailed story about your contributions, and who clearly wants to see you succeed — can tip a close decision in your favor or reinforce a positive impression from the interview process.

Direct supervisors who know your work well. A manager who you worked closely with for more than a year is typically the strongest category of reference. They have direct, specific knowledge of your performance, can speak to your growth, and carry the authority of someone who held you accountable for results.

Peers who collaborated closely with you. Colleagues who worked directly with you on significant projects provide a different perspective than management references — they speak to collaboration, communication, and day-to-day working style. Peer references are often valued specifically for this different angle.

People who are enthusiastic, not just willing. A reference who feels obligated to provide a reference is different from a reference who genuinely wants to advocate for you. Before listing someone, have an honest conversation about whether they feel they can provide a strong, positive reference. Someone who hesitates should not be on your list.

People with credibility in their field or organization.A reference from a well-known organization or from someone with a senior title carries more weight than the same words from an unknown source. When all else is equal, lean toward the reference with more visible credibility.

Never surprise a reference. Contact them before you list them, explain the role you are applying for, and ask explicitly if they are comfortable providing a strong positive reference. This conversation also gives them the context they need to speak specifically and relevantly.

Send your references the following before the check: your updated resume, the job description for the role, one or two specific accomplishments you would like them to emphasize, and any known concerns from the interview process that they might be asked about. Prepared references produce better references — not because they are coached to lie, but because they have the context to speak specifically rather than vaguely.

If you know what qualities the employer is focused on based on your interview conversations, share that framing with your references. If the hiring manager emphasized the importance of cross-functional collaboration skills, a reference who has relevant examples of your collaboration work should be foregrounded over a reference who knows primarily about your individual output.

Candidates who are conducting a confidential search, who left a job on difficult terms, or who have gaps in their work history face added complexity around references. None of these situations are insurmountable, but they require some forethought.

For confidential searches, skip-level managers, former managers, and peer colleagues are all viable alternatives to your current direct manager. Most employers accept explanations that you are searching confidentially and that involving your current manager would compromise that.

If you left a previous job on genuinely bad terms, you almost certainly should not use anyone from that organization as a reference. Even if a colleague there would speak positively about you, the association with a contentious departure creates context that works against you. Focus on building strong references from roles where your departure was positive.

Finally, always follow up with your references after they have been contacted. A brief thank-you for their time, and an update on the outcome, maintains the relationship and demonstrates the same professionalism and follow-through that your references told the employer you have.
