It came out of the blue. You submitted references after what felt like a strong interview and were waiting to hear the good news. But then you find out one of your former bosses gave you a bad reference. Is it over? Have you lost the job?
Although I wish I could give you a simple “yes” or “no” answer, the truth is it all depends on a few things. And I’ll get to that soon. But more important is what you need to do the next time (if this job doesn’t work out) to avoid this situation.
In order to do their job, reference checkers ask questions of the people whose names you provide them on a reference sheet. They may also find other sources on their own if needed, but in most cases the names you give them are enough.
Do job references really matter? Sometimes more than you know. And sometimes less. If that sounds confusing, it kind of is confusing since you can’t be sure of your potential employer’s policies. Or lack of policies.
If possible, you should call your references before your job interview. You want to make sure that they are available and willing. And that you have their correct contact info.

If an employer is checking your references, does it mean you got the job? Not necessarily.
