What Is Interview as a Service? How It Works, Benefits & Real-World Use Cases [2026]

Interview as a Service, or commonly known as IaaS, is a great alternative to get domain experts for your company’s hiring needs. In simple terms, an Interview as a Service means getting some outside experts to conduct interviews and screen candidates rather than relying on your internal resources. 

The expert panel will conduct the interviews, score them fairly, and send a clear report for further assessment. You don’t need to put your internal team and expenses into running every single interview yourself. 

To understand more about what Interview as a Service is, let’s take a scenario of a small company that doesn’t have an accountant. In such a case, the company is going to pay an outside accounting service provider to get the job done. 

Interview as a Service works the same way, but for interviews. You’ll have a trained professional outside of the company to conduct the interviews (whether technical or non-technical ones) & your team makes the final decisions based on their reports. 

Interview as a Service is different from a staffing agency that typically finds and places candidates for you. IaaS does something different, where the team handles the interview itself. 

Your internal team and management will still be in control of screening and taking the final hiring call. IaaS solves the major burdening stage of hiring that takes up most of the time and is hardest to handle on a consistent basis.

Why Companies Started Using Interview as a Service?

Over the past couple of years, hiring has become a challenge for every other organization in multiple ways. Interview-as-a-Service is designed to solve the challenge of interview burden. 

Your Team Doesn’t Have Time to Interview Everyone

With more and more job openings in an organization, the best professionals, engineers, and managers invest most of their time in interviews. This simply means that operations and their tasks get impacted because of this burden. Some companies have proven to save their work hours and expenses by outsourcing the stage to interview-as-a-service providers. Internal staff and resources get more time and bandwidth to focus on their own operations and responsibilities. 

Different Interviewers Score Candidates Differently

With multiple individuals taking interviews, everyone judges candidates on the basis of their own perspective. This becomes a major problem of interviewer bias and doesn’t ensure fair screening. In other scenarios, one interviewer might be tough, while others can be relaxed as well. Hence, the final hiring decision mainly depends on who is asking the questions instead of the candidate’s skills. 

Some Roles Need Skills Your Team Doesn’t Have

If you’re hiring for a technical role, there can be plenty of Interview as a Service benefits. No matter if it is for a developer, cloud engineer, or machine learning specialist, interview-as-a-service can be a worthy answer to your interview process needs. It is even helpful if your internal team lacks the knowledge and skills that a technical interviewer actually needs. The IaaS hiring model allows you access to people who are real experts in technical or non-technical fields. 

Hiring Needs Can Jump Up Fast

A company needs multiple new candidates every month, with more clients and contracts coming in. It is not possible to stretch or shrink your internal hiring team quickly with every new job opening. An on-demand interview service will connect you with the experts who are already waiting to take over immediately.

• You are recruiting for the skills that your internal pool of interviews fails to understand. 
• Your company’s hiring volume keeps changing every month on a project-to-project basis. 
• There is a problem of interviewer bias because your team scores candidates very differently and not according to the same criteria.
• Your company is growing too fast and lacks the ability to keep building a new team at the same pace. 

In case none of the above ones hold true for your organization, you need to check with the experts if there is a need for such service or any other support.

Frequently Asked Questions

What does Interview as a Service mean in simple words?

Interview as a Service means having a pool of interviewers from outside who can conduct interviews for you, rather than relying on your internal team and resources. The domain experts coming from outside will handle the burdensome work of taking interviews, scoring candidates, and preparing their reports. This will give your internal managers and hiring department the right direction for making the right decision, and let good talent come into the organization. Interview-as-a-service (IaaS) only handles the interview process for any organization. 

How is Interview as a Service different from a staffing agency?

In reality, the staffing agency is all about finding candidates and placing them in your company as per the requirements.

In any case, your internal leadership and relevant managers will be the ones making the final hiring decisions. 

What are the main benefits of using Interview as a Service?

Is Interview as a Service only for tech companies?

No, there is no specific niche limitation when it comes to using the IaaS hiring model for organizational-level hiring.
