Why Enterprise Companies are Shifting to IaaS for hiring top talent

According to a survey by Market Research Future, the interview scheduling software industry was valued at $1.73 billion in 2022. With a compound annual growth rate (CAGR) of 7.3 percent, it is expected to reach $3.5 billion by 2032. This is because companies are now increasingly switching to these Interview as a Service (IaaS) tools to make their recruitment process more efficient.

The reason for this switch has increased further with the rise of Artificial Intelligence (AI), which has made these tools better. AI helps recruiters make decisions faster without affecting the quality of recruitment. These tools save time and money and reduce the chances of a bad hire. According to research by the Society for Human Resource Management(SHRM), a bad hire can cost a company six to nine months of an employee’s salary. 

So, in this article, we will explore why enterprise companies are shifting to IaaS for hiring top talent. Before that, however, we have to delve into what IaaS is.4

What is Interview as a Service?

Interview as a Service (IaaS) is a hiring solution provided by Software as a Service (SaaS) companies for their clients. While some IaaS tools may offer end-to-end hiring solutions, others only help their clients with a specific part of the recruitment process. IaaS tools can help recruiters conduct technical, behavioral, and domain-specific interviews or all of them.

Interview as a Service tools have also started to amalgamate Artificial Intelligence, which can help interviewers conduct structured interviews within seconds, a task that used to take hours. IaaS also provides several benefits over traditional methods.

Why Companies are Shifting to IaaS

Over the years, recruitment has undergone massive change. Earlier, the recruitment process was heavily influenced by the individual’s core skills. However, now companies have also started to prioritize soft skills such as communication, leadership, and teamwork, among others. 

In addition, researchers have also shown that bias in the recruitment process can also affect the quality of hiring. This is why IaaS tools have features such as structured interviews, recording, and transcribing to combat bias.

So, here are the reasons why enterprise companies are shifting to IaaS to hire top talent.

Scalability 

One of the best advantages of any SaaS tool is that it is very easy to scale when the demand for it increases. On the other hand, it can also be scaled down when the demand for hiring is not high. In addition, these tools also ensure that the scalability does not affect the hiring quality. This feature allows the company to efficiently hire during mass hiring, seasonal hiring

Access to Expert Interviewers

IaaS tools also give companies access to a pool of expert interviewers who are well-trained in the tool. It is essential for companies that do not have the necessary infrastructure and manpower to run the tool efficiently. These interviewees are industry experts with years of experience hiring for industry-specific roles. They have the capability for conducting high-quality interviews using structured interviews that allow for unbiased evaluation of candidates.

Cost Efficiency

As mentioned earlier, hiring costs both time and money. However, if not done properly, it can greatly burden the company. One of the biggest cons of an inefficient recruitment is that it leads to bad hires. It leads a company into an endless cycle of continuously conducting bad hires, which leads to high interviewer costs, lost productivity, and hiring delays. IaaS can save massive costs by eliminating the need for full-time interviewers, lowering hiring-related operational costs, and using a flexible costing model.

AI-Powered Assessments

Another advantage of IaaS is that it now harnesses the power of Artificial Intelligence to automate several aspects of the recruitment process. This becomes very helpful during boring and mundane tasks where the probability of a human committing an error is high. Such AI-backed tools can help recruiters pre-screen by sorting out the most suitable CVs and creating a structured interview format. During interviews, these tools also record and transcribe the entire Interview, which can later be shared with all the stakeholders so that they can analyze the candidates and the interviewer.

Seamless Integration with ATS

A good IaaS platform also ensures that it can be easily integrated with its client’s Application Tracker System (ATS). Such IaaS tools help streamline the recruitment process and ensure recruiters do not have to spend additional time training on new Software. 

Some advantages of IaaS tools integration with ATS are as follows:

• Automatic data sync between the IaaS and ATS.
• Makes a centralized system from where every hiring detail can be monitored.
• Helps in scheduling interviews and forming structured interviews.
• Makes decision-making faster 
• Evaluation can be shared with every stakeholder involved in the recruitment process.

Improved Candidate Experience

A good recruitment process values the candidate’s experience. Companies that provide a positive experience for candidates enhance their brand image, which leads to word-of-mouth publicity that attracts the top talent across the industry. 

A good recruitment process is fast, provides clear feedback, automates scheduling, and streamlines assessments. It also reduces the risk of introducing bias and ensures that every candidate is treated fairly.

Diversity & Inclusion in Hiring

Several types of research have indicated that diversity and inclusion in a workplace not only improve the work environment but also increase the company’s revenues and profits. However, in the traditional interview setup, people from minorities and underrepresented groups were victims of bias, especially subconscious and unconscious bias. This is where IaaS solves the problems with features such as structured interviews, blind CVS, anti-bias language detection, and much more.

Reducing Recruitment Team Workload

In recent years, recruiters’ roles have also changed massively. Earlier, their major responsibility was to conduct hiring. However, companies have now started using recruiters in policy-making to make the workplace more efficient. This is where IaaS is of immense help, especially for boring and repetitive tasks such as interview scheduling, sorting CVs, creating a question set, and recording interviews, which negates the need for taking notes.

The rise of interview-as-a-service (IaaS) platforms has been rapid, with a host of platforms offering their services. While some offer end-to-end hiring solutions, others only help with a specific part of it, and some only help with technical platforms (HackerRank, CodeSignal, and Karat).

One such platform is BarRaiser, which offers end-to-end hiring solutions. Our tool guarantees to take your hiring to the next level. Firstly, with our AI Interview Copilot, an interviewer gets a digital assistant who helps them navigate the interview process.

Even before the Interview begins, an interviewer can simply ask the AI Interview Copilot to create a structured interview question format within seconds. An example of this would be as follows:

‘Create a questionnaire for the post of a senior product manager. The candidate should have at least five years of experience. Candidates should have experience with SaaS, B2B/B2C products, and platform development and should also be proficient in tools such as SQL, Google Analytics, Mixpanel, and Tableau.’

After this, the tool takes seconds to create a thorough question set. However, that is not all. During an interview, if the interviewer runs out of questions, they can simply ask the interviewer to create new questions by going through the candidate’s CVs or the interview context (as the entire Interview is recorded and transcribed).

Moreover, our tool also monitors the behavior of both the candidate and the interviewer. The reasoning behind this is simple: a recruitment process is efficient as long as there is no bias present. This is why our AI bot creates two reports. The first is created with the recruiter’s help, and the candidate is judged on multiple metrics. The second report, however, is created by the AI on its own on the interviewer’s behavior to ensure that no candidates suffer from bias. This report is shared with all the stakeholders of the interview process, through which the interviewer can also give some feedback.

Using BarRaiser, we guarantee quality hiring that will bolster diversity and inclusion. BarRaiser is the best AI interview platform that features structured interviews and tools to ensure quality hiring while eliminating recruitment bias. With BarRaiser’s support, you’ll be well-equipped to build a strong team of sales associates who will drive sales and deliver exceptional customer service.
