Short answer
Candidate screening is how you narrow a pile of applicants down to the few worth interviewing. Do it in this order: write down 3 to 5 must-haves, ask knockout questions with the application, read resumes against the must-haves, give a short assessment, do a 15-minute phone or video screen, then invite the best few to interview.
Use the same steps and the same questions for every applicant. That's what keeps your screening fair and legal.
If you hire without an HR team, screening is probably the part that eats your week. You post a job, 60 people apply, and you're reading resumes at 10 pm trying to guess who's worth a call. Here's a simpler way to do it.
What is candidate screening?
Candidate screening is everything you do between "they applied" and "they're coming in for an interview." It rules people out quickly and fairly, so you spend interview time only on the people most likely to do well and stay.
Screening decides who gets an interview. A good screen is short for the applicant and takes you a few minutes per person. It also looks at the same things for everyone.
How to screen candidates in 6 steps
Each step costs a little more of your time than the one before, so the early steps should rule out the most people:
| Step | What you learn | Your time per applicant |
|---|---|---|
| 1. Must-haves | What a "yes" looks like, before you read anything | Once per job |
| 2. Knockout questions | License, schedule, driving, pay range | Seconds |
| 3. Resume read | Relevant experience and steady work history | 1 to 2 minutes |
| 4. Short assessment | How they're likely to work: reliability, pace, people skills | A minute to read the result |
| 5. Phone or video screen | How they talk, and whether they still want the job | About 15 minutes |
| 6. Score and invite | Who your top few are | A few minutes per job |
1. Write down 3 to 5 must-haves
Before you open a single resume, write the 3 to 5 things a person must have to do this job. A license, a schedule, a skill, a trait like "stays calm with upset customers." Anything else is a nice-to-have. If you're not sure what really counts, our post on deciding what disqualifies a candidate walks through it.
2. Ask knockout questions with the application
Turn the must-haves you can check with a yes or no into 3 or 4 short questions on the application. "Do you have a valid driver's license?" "Can you work Saturdays?" "Does the pay range in the ad work for you?" Anyone who answers no to a true must-have is out, and you didn't have to read their resume to find that out.
3. Read resumes against the must-haves
Now read what's left, with your must-haves list next to you. You're checking for relevant experience and a work history that makes sense, not hunting for the perfect resume. Our list of resume screening pitfalls covers the common traps, like rejecting every gap.
4. Give a short assessment
A resume tells you where someone has worked. A short personality assessment, sent before the interview, adds what it can't: who's likely to be reliable, how they handle pressure and how they deal with people. Read the result next to your must-haves, and use it to pick your interview questions.

5. Do a 15-minute phone or video screen
Talk to the people who made it this far before you book an hour with anyone. Ask the same 4 or 5 questions each time: why this job, what their last job was really like, their schedule, and one question from the assessment result. A one-way video interview works too: they record answers when it suits them, and you watch when it suits you. Our tips on phone screening candidates cover the call itself, and our guide to the one-way interview covers the video option.
6. Score everyone the same way, then invite the top few
Give each must-have a simple score, like 1 to 3, and score every applicant on the same list. Then invite the top 3 to 5 to a structured interview, where everyone gets the same questions. A 2022 review of decades of hiring research (Sackett and others, Journal of Applied Psychology) ranked structured interviews as the strongest predictor of job performance among the hiring methods it studied. SIOP explains the findings in plain language.
Keep screening fair and legal
The legal test for any screening step is simple to say: it has to be related to the job. The EEOC says a test or selection procedure that screens out a larger share of people of one race, color, religion, sex or national origin is illegal unless it is "job-related and consistent with business necessity" (EEOC, Employment Tests and Selection Procedures).
To stay on the safe side:
- Use the same steps and questions for everyone who applies for the same job.
- Only screen for things the job needs. Don't ask about age, family plans, religion or health.
- If you use a background check company, tell the applicant in writing and get their written permission first, as the EEOC and FTC guide explains. Your state may add its own rules, so check them.
How screening changes by job
The 6 steps stay the same. What changes is the must-haves list and what you ask in each step.
Car sales
Dealerships screen car sales applicants for drive, coachability and how they handle rejection, more than for past sales experience. Knockout questions cover weekends and evenings and a valid driver's license. Our guide to hiring car salespeople has the screening questions and a role play to use, and here's how IdealTraits works for car dealerships.
Caregivers
Home care agencies screen caregivers for reliability first, because a no-show means a client goes without care. Check certifications and driving in the knockout questions, then use an assessment to see who's likely to show up and follow a care plan. Our caregiver interview questions include good answers and red flags.
Roofing storm sales reps
Roofing companies screen storm sales reps for persistence, comfort with commission pay and willingness to travel after storms. The job means knocking on doors all day, hearing "no" constantly and getting paid mostly on commission, so screen for that directly. Ask in the knockout questions whether they're OK with commission pay, travel after storms and long days outdoors. Use an assessment to find people who are persistent and comfortable starting conversations with strangers. Then do a short phone screen with one role play: "A homeowner says they already have a roofer. What do you say?" Some towns require a permit to sell door to door, so check the towns you work in and tell applicants if they'll need one.
Accounting and law firms
Accounting and law firms care most about accuracy. A typo on a return or a filing costs real money, so they screen for careful work first, then discretion and how someone treats clients. Knockout questions cover busy season hours, like tax season for accounting firms, and any software the job needs. A short assessment shows who's likely to be careful and steady with detail work. In the phone screen, ask about a time they caught a mistake before it went out, and listen for specifics.

FAQ
How long should candidate screening take?
For most hourly and entry-level jobs, aim to screen each applicant within a day or two of applying. Good applicants are often talking to other employers, and a slow screen loses them. Most of the time goes into the 15-minute phone or video screens, which is why the earlier steps should rule out as many people as they can.
