High-volume hiring happens when you need to fill many roles in a short time. You might be opening a new store or starting a large project. When this happens, you get hundreds or even thousands of applications. Reading every resume is impossible. You need a way to find the right people without spending weeks on the task.
The main problem in high-volume hiring is noise. You have too much data and not enough time. You need to find a way to filter out people who do not fit the job. This is where you need to test candidates at scale. By using tests early in the process, you can focus your time on the best people.

Key Takeaways
Testing is the best way to prove a person can do the work. A resume only tells you what someone says they did. A test shows you what they can actually do. When you test candidates at scale, you create a fair system for everyone.
Here are some reasons why testing at scale is a good idea:
If you do not have a system to test candidates at scale, your hiring team will get overwhelmed. They will make mistakes because they are tired. A good testing system keeps the process moving fast.
You have two main ways to send tests to your applicants: email and SMS. Both have pros and cons. In a high-volume hiring situation, you should use both to reach as many people as possible.
Email is a standard tool in business. It allows you to send long instructions and links to complex tests. Most people expect to hear from recruiters via email. However, emails can get lost in spam folders. People might not check their email for several hours or days.
Bulk SMS is a powerful tool for high-volume hiring. Most people have their phones with them at all times. A text message gets noticed much faster than an email. When you use bulk SMS, you get higher response rates. This is very helpful when you need to hire people quickly.
Bulk SMS helps you reach a large group of people in seconds. It is direct and personal. For many jobs, especially in retail or labor, candidates prefer text messages. They can click a link in the text and take a short test on their phone.
Using bulk SMS also shows that your company is modern. It makes the hiring process feel fast. If a candidate is looking for many jobs, the company that replies first often wins. Bulk SMS makes sure you are that company.
To manage many applicants, you need a tool that handles bulk actions. You cannot send one email at a time. That would take too long. You need a system where you can upload a list of names and contact details.
When you are ready to send to multiple candidates at once, follow these steps:
Refhub makes this process simple. It handles the hard work of sending messages so you can focus on the results. By sending tests to everyone at the same time, you keep your hiring timeline on track.
Once you test candidates at scale, you will have a lot of scores to look at. You should not grade these by hand. Use a system that scores the tests automatically.
Automated scoring gives you a list of candidates ranked from highest to lowest. This makes it easy to see who you should call first. You can set a minimum score. Anyone who scores below that number is automatically moved out of the process. This helps you manage the high-volume hiring load without extra stress.
To get the best results when you test candidates at scale, you should follow these rules:
How do I start high-volume hiring? You start by setting up a workflow. This includes a job post, a way to collect resumes, and a system to test candidates at scale.
Is bulk SMS better than email? Bulk SMS usually has a higher open rate. It is better for quick communication. Email is better for sending long documents or complex information.
What kind of tests should I use? Use tests that match the job. For a desk job, use a typing or software test. For a customer service job, use a situational judgment test.
Can I use these tools for any job? Yes. Any job that has many applicants can benefit from automated testing. It helps you find the best people in any field.
Managing a large number of applicants does not have to be a nightmare. When you use the right tools, you can turn a mountain of resumes into a small list of great people. Testing is the key to this change. It gives you the facts you need to make smart choices.
By using bulk SMS and email, you reach candidates where they are. You make it easy for them to show you their skills. This makes your brand look good and helps you fill roles faster. High-volume hiring is a game of speed and accuracy. Testing at scale helps you win at both.
