Absolutely, here’s the short answer: you should add people who have directly observed your professional skills, work ethic, and contributions in a work-related setting. Think former managers, supervisors, colleagues you’ve collaborated with closely, or clients who can speak to your performance. Avoid friends, family, or anyone who hasn’t worked with you in a professional capacity.
In practice, I always recommend reaching out to at least two former managers and one peer or direct report. Managers can confirm your reliability, leadership, and growth, while peers can give a more balanced view of your teamwork and communication. If you’re early in your career, former internship supervisors or professors who oversaw your projects also work well.
Here’s a quick breakdown of reference types and their typical strengths:
| Reference Type | What They Can Speak To | Best For |
|---|---|---|
| Former Manager | Performance, growth, accountability, leadership | Mid-to-senior roles |
| Peer/Colleague | Collaboration, problem-solving, daily work ethic | Any role |
| Client/Customer | Service quality, project management, professionalism | Client-facing roles |
| Professor/Academic Advisor | Academic ability, research, discipline | Entry-level or internships |
| Mentor (professional) | Guidance, soft skills, career trajectory | Career changers |
One crucial step: always ask permission before listing someone. Briefly explain the role you’re applying for and confirm they’re comfortable providing a positive reference. Then, remind them of key achievements or projects you worked on together so they can tailor their feedback. This small courtesy makes a huge difference in the quality of the reference.
Also, keep your list narrowed to three to five people. Most employers will only contact two or three, but having a well-curated set shows you’re thoughtful and organized. And if you have a gap in your work history, a volunteer coordinator or a long-term client can fill that spot effectively.

For me, it’s all about the people who saw me grow. I’d pick a former boss who challenged me and a teammate who relied on me. They know my real strengths and weaknesses, not just the polished version. I also make sure to pick someone from a recent role—like within the last three years—so their memory is fresh. If you’re switching industries, a supervisor from a volunteer gig or a side project works too, as long as they can describe your transferable skills like punctuality, problem-solving, or adaptability. Just don’t overthink it—keep it to three solid names, and always check in with them first.

I’d focus on the person who saw me handle a tough situation. That’s usually a manager from a high-pressure project or a client I went above and beyond for. They can speak to how I react under stress, which is gold for any hiring manager. I also avoid anyone I’ve only had casual chats with—like a coworker from the break room. Depth of relationship matters more than title. For me, one strong reference who gives specific examples beats three generic ones every time.

I look at it this way: your references should mirror the people you’d work with in the target role. If you’re applying for a team lead position, include a former boss and a direct report. If it’s a sales role, a client who saw your negotiation skills is perfect. I also like to include a peer from a different department—it shows cross-functional collaboration. Just be strategic: pick people who can speak to the exact skills listed in the job description. And always brief them on the role so their stories align with what the employer wants to hear.

As someone who’s worked multiple freelance gigs, I on project clients and repeat collaborators. They’ve seen my deliverables, deadline adherence, and communication style. I also add a former coworker from a past full-time job who can vouch for my reliability. The key is variety: one client, one peer, and one mentor. But I never list someone who hasn’t worked with me in the last two years. Outdated references lose impact. And I always send a short note like “Hey, I’m applying for a project manager role—here’s what we accomplished together” so they’re ready to talk.
