References usually come up late, when you are nearly hired and least inclined to think carefully. A prepared reference can confirm exactly what the employer is unsure about. An unprepared one can be vague enough to cause doubt.
Who to choose
In rough order of weight:
- A direct manager who saw your work closely.
- A senior colleague or project lead who relied on your output.
- A client or customer, strong for consulting, sales and service roles.
- A professor, coach or volunteer coordinator, for students and career changers.
- A peer, as a supporting voice rather than your main reference.
Avoid friends and relatives, and avoid anyone who only knew you socially. Employers notice.
Choose for relevance, not seniority. A team lead who watched you solve problems every week is far more useful than a director who can only confirm your dates.
How to ask
Ask before you list anyone. A surprise call reflects badly on you.
Hi Priya, I’m interviewing for a customer success role at a SaaS company and I’m at the reference stage. Would you be comfortable speaking to my work on the onboarding project? Completely fine to say no.
The phrase “comfortable speaking to” matters. It gives someone a graceful way to decline, which protects you from a lukewarm reference.
Brief them properly
Once they agree, send a short message with:
- The role and company, plus the job posting link
- Two or three things the employer seems focused on
- One or two specific achievements you worked on together, with numbers
- Roughly when they should expect contact, and how
This takes five minutes and transforms the quality of the call. People want to help; they just need the material.
Keep them warm
- Tell them the outcome, whether you got the role or not.
- Thank them specifically.
- Check in occasionally so the next request is not a cold one, as described in our guide to networking.
- Offer to return the favor.
If your current employer cannot be told
Normal, and employers understand it. Offer references from previous roles, clients or colleagues who have left, and ask that your current employer only be contacted after an offer. Say it plainly: “I’d prefer my current employer isn’t contacted until we have an agreement, for obvious reasons.”
If a past manager will not give a reference
Some companies have a policy of confirming only dates and job title. That is common and not a red flag; say so upfront. If a relationship ended badly:
- Choose someone else senior from the same period.
- Be honest and brief if asked: “My manager and I disagreed about priorities toward the end, so I’ve suggested the team lead I worked with daily instead.”
- Make sure your other references are strong enough to carry the picture.

What employers actually ask
Typically: dates and role, what you worked on, how you handled pressure or conflict, whether they would hire you again, and sometimes a weakness. Some use written forms; many now use short calls or automated questionnaires.
Background checks are a separate step. They verify employment dates, education and sometimes criminal records, with your written consent. Keep your resume dates accurate, because mismatches cause more withdrawn offers than anything a reference says. Our ATS-friendly resume guide covers getting those details right.
Frequently asked questions
How many references should I have ready?
Three, with a fourth in reserve. Have their current job titles, email addresses and phone numbers ready in one document.
Should I put “references available on request” on my resume?
It is unnecessary; employers will ask. Use the space for your achievements instead.
Can an employer say something negative?
They can say what is true and factual. Most limit themselves to dates and role to avoid risk. This is exactly why choosing and briefing references matters.
