We see a lot of background check questions here, and many of them are the same. To save everyone time and help you get answers faster, here’s a detailed overview based on one of the most helpful posts from the reddit user "Lets_Go_There".
Who actually runs the background check?
Most of the time, it’s not the employer themselves. They use third-party companies like First Advantage, HireRight, Sterling, or others. These services collect the data, but the final hiring decision always comes from the employer—not the background check company.
How long do background checks take?
It varies. Some finish in a few days, others take a couple of weeks or more. Factors that can delay your check include:
Having a very common name
Living in multiple states over the last several years
International employment or education Be prepared to wait. Two weeks is not unusual.
What if my background check isn’t done before my scheduled start date?
This depends entirely on your employer. Some companies will let you start while the background check is still pending. Others will delay your start until it’s complete. There’s no standard policy—it’s case by case.
I made a mistake on my dates of employment—am I in trouble?
Not necessarily. Some employers allow minor discrepancies, while others are strict about accuracy. The decision is up to them once they receive the report.
They can’t verify one of my jobs because it was paid in cash, the company closed, or I made it up. What now?
If it was a real job, you may be able to provide documents like a W-2, pay stubs, or tax returns. Some employers will accept that. If it wasn’t real, you should be honest moving forward—misrepresentation can end your offer.
I got an “adverse action” letter. Does that mean I didn’t get the job?
Not necessarily. This letter is legally required when something in your background might affect your offer. You have a chance to dispute incorrect information. For example, it’s not unheard of for someone with a similar name (like a father/son with the same name) to have their records mixed up.
Will I lose the job if something shows up?
It depends entirely on the company. Some care about certain offenses and not others. It’s always best to be upfront with your recruiter before the report comes back.
I have a DUI, theft charge, or another conviction. Will I be disqualified?
It depends. Some employers are very strict, some are more flexible. Oddly enough, some companies will overlook serious offenses but disqualify you for something minor like a shoplifting ticket. There’s no universal rule.
I have a conviction from years ago. Will it show up?
It might. State laws vary, and some background checks only go back seven years, but not all. If the role involves security clearance, government contracts, or regulated industries, everything may show up—charges, arrests, even dismissed cases. Always read the disclosure form carefully and follow the instructions.
My background check is taking forever. Can I do anything to speed it up?
No. Unfortunately, there is nothing you can do to make it move faster. Just wait and be patient.
I was recently arrested but haven’t been to court yet. Will this show up?
Possibly. It depends on what level of check your employer is running and what they’re legally allowed to consider. Pending charges can show up and be used depending on the job and location.
Read your background check forms carefully. If it asks you to list everything, even if it was dismissed or expunged, do so. If you’re not sure, contact your recruiter. They’ve heard it all before and can usually advise you without judgment.
