Best Interview as a service platforms in 2025

The hiring industry has been transformed within a few years, all thanks to Artificial Intelligence. Recently, a host of tools have been developed that use AI’s power to increase the interview process’s efficiency.

Some tools provide Ai interview copilot, which acts as a virtual assistant to the interviewer, the candidate, or both, depending on the software. However, some companies offer what is called Interview as a service (IAAS). 

A report by Insight Partners predicted that the Video Scheduling Software industry was worth $250.06 million in 2020 and is expected to reach $891.86 million by 2030 at a Compound Annual Growth Rate(CAGR) of 17.23 per cent. 

The Interview Scheduling Software industry is worth $618.3 million and is expected to reach $10.8 billion by 2033, an impressive CAGR of 33.1 per cent. Even the mock interview software industry is worth $2.06 billion.

This proves that companies are using AI hiring tools for various services, such as IAAS. So, what is an Interview as a Service, and what services are provided by such tools?

What is Interview as a Service?

Interview as a service is a hiring solution presented to companies that either lack the bandwidth or manpower in the hiring department to conduct recruitment through AI tools on their own. Under this model, an external provider takes over the entire recruitment process, from resume screening to post-interview feedback.

The external provider has a pipeline of talented recruiters who help conduct the interviews. The client usually only has to provide job details, the number of vacancies, and the number of years of experience. Some clients could also provide additional requirements such as leadership qualities, teamwork, and cultural fit.

The IAAS company starts screening resumes based on the job requirements. Companies usually work on a hybrid model, using both human recruiters and AI tools to select the most suitable resumes for the Interview.

It is here that the main job of an IAAS begins. After the shortlisting of resumes, the interview process begins, where the AI bot plays a significant role. During the Interview, it acts as a virtual assistant, providing all the required information to the interviewer in real-time. This includes answering questions and recording and transcribing the Interview.

The tool should help the interviewer provide detailed feedback after the Interview. This report should be generated without bias to maintain the sanctity of the recruitment process.

Advantages of using IAAS tools

Cost and time efficiency 

The greatest advantage of using an Interview as a Service tool is that it saves both cost and time. The entire recruitment process involves certain boring, mundane, and repetitive tasks. A human recruiter could have his efficiency hampered by doing such tasks. This increases the time of the hiring, thereby increasing the hiring costs.

This is where IAAS tools are of great use. Firstly, they take over the boring parts of the recruitment process, such as scheduling, recording, and transcribing interviews. This allows the interviewer to focus on more important things, such as candidate feedback.

Improved candidate experience 

Your company’s recruitment process is heavily dependent on the candidate’s experience. The better the experience, the better the chances of getting the most talented candidates. So, IAAS helps a lot by creating an environment of professionalism by automatically scheduling interviews and ensuring their time is not wasted.

This improves the company’s image in recruiters’ minds. Candidates with better experience of the process are also more likely to recommend others to join the company, which gives it free word-of-mouth publicity.

Scalability 

A major problem for the hiring industry is its volatility. During the hiring season, the recruitment department could have its hands full, while its workload would be much reduced in the off-season. Meanwhile, a startup looking to scale up after a major round of funding would like to recruit as many people as possible quickly.

So, an IAAS platform with an extensive network of expert interviews and an AI tool can easily help companies scale in an instant. They can also scale down when their client no longer needs to do mass hiring.

Standardization

One of the most challenging things for any service provider is ensuring a standard-quality experience for all their clients. However, doing so is easier said than done due to the human factor, as some mistakes can always happen. This is where IAAS tools use the power of Artificial Intelligence to reduce errors, ensuring the quality of the interview process is maintained.

Standardization also allows companies to compare candidates to industry or role-specific standards. This will allow companies to fine-tune their interview process continuously, eliminating all the system’s imperfections.

Reduces bias 

Perhaps the biggest reason behind the rise of IAAS platforms is their efficiency in eliminating or minimizing bias in the interview process. The US Department of Labor states that a bad hire costs 30 percent of an employee’s salary. So even with a ten percent bad hire rate, companies can lose a lot of money while also decreasing efficiency.

IAAS tools have no inherent bias as they have no emotions. This means that every employee is judged on the same metric. Moreover, IAAS platforms also deploy a Structured interview format, which means all the candidates are given the same questions to curb bias during the interview process.

Easy integration with other tools 

One of the most underrated strengths of any online platform is how easy it is to integrate with other tools. For example, a tool that is not easily compatible with a company’s Application Tracker System (ATS) will find few takers, however good it may be in other areas.

Such tools should also be compatible with other service tools that the company may be using. For example, an organization might use LeetCode or HackerRank while hiring software developers. This is why every company today opts for IAAS services that offer cross-platform integration without any effect on recruitment.

Best IAAS platforms 

BarRaiser 

One of the best IAAS tools for companies looking to improve their hiring process is BarRaiser. The tool offers end-to-end solutions and a plethora of services. So, how does one use BarRaiser? The process starts with clients uploading job descriptions on their platform. Following this, the AI tool helps select the most suitable CVs for the Interview.

However, it was during the Interview that the tool became most useful. Using its AI interview Copilot, interviews can create a set of questionnaires by simply giving details such as job description, number of experience, number of interview rounds, and parts of the Interview ( introduction, technical expertise, etc). Interviewers can also create new questions by asking the AI bot to go through the candidates’ resumes or even the interview context.

Post-interview, the tool asks the interviewer to rate the candidates on each question. This creates a detailed assessment of each candidate, allowing recruiters to make better judgments while hiring. This process is done by a series of expert interviews rigorously trained on BarRaiser, which ensures that it is swift and accurate.
