Phone Screening or AI Screening – Which Is the Smarter Choice for Your Business?

In recent years, with the hiring process becoming even more competitive, it is more important now than ever to identify the right talent within the shortest time possible. With competition for top talent at an all-time high, recruiters are often faced with a crucial decision early in the hiring process: Should they continue to use conventional phone screening or embrace advanced AI screening technologies?

Telephone interviewing has always been a part of the recruitment process as it provides the possibility of a friendly live conversation with the applicant. However, as the need for fast recruitment increases especially for high-volume hiring, this method can be cumbersome, and costly. Now that the traditional methods of recruiting are not that effective, technological advancements in AI screening have emerged in the market, such as PreScreen AI. This interview bot is intelligent and automates the initial selection process, allowing the recruiter to make better decisions instead of being stuck in front of the computer all day.

In this article, we seek to uncover what AI screening is all about, pit it against phone screening, look at the advantages and disadvantages of both methods, and guide you on when to use either method or a combination of both to solve your hiring problems.

Whether your goal is to increase effectiveness, decrease the time to hire or optimize the candidate experience. these screening methods will assist in creating a recruitment program designed for success.

Phone Screening – The Traditional Approach

Telephone interview has long been considered a gateway in the process of recruitment. It is an effective way the recruiters can have direct communication with the candidates and get prompt understanding of their persona, competency and fitness for the job. In this article, we’ll explain how it works and offer an overview of some key strengths and weaknesses.

How Phone Screening Works

Recruiters usually make appointments with candidates after considering the resume and applications submitted. The calls tend to have scripted questions, concerning the candidate’s experience, qualifications, availability and the requirements of the position they are seeking. Recruiters evaluate the candidate’s verbal communication, passion, and cultural fit through conversation. From the phone screening process, recruiters determine whether to take the candidate to the next stage.

Benefits of Phone Screening

• Personalized evaluation. This is of particular value in job interviews because during a live conversation a recruiter is free to adjust the types of questions depending on the candidate’s answers and spend more time discussing certain issues.
• Assessing communication skills. Candidates’ tone, clarity, and professionalism during the call give recruiters a strong sense of their interpersonal abilities.
• Building relationships. One warm communication at the beginning of the screening process can positively influence the candidate’s perception of the company especially for positions that involve direct dealing with the public.

Challenges of Phone Screening

1. Time-consuming. The calls usually last 20–30 minutes each. It could take 50+ hours of screening 100 candidates for a single role, not including scheduling time.
2. Scheduling difficulties. Coordinating times between recruiters and candidates can lead to delays, especially for candidates in different time zones.
3. No-shows. It’s common for candidates to miss scheduled calls, wasting valuable recruiter time.
4. Scalability issues. For high volume hiring, where thousands of candidates may apply for a single role, it becomes impractical to do phone screening.
5. Inconsistent evaluations. Standardized questions won’t eliminate individual recruiter biases or their fatigue when judging candidates.

Despite its advantages, phone screening does not meet the challenge of the contemporary fast-pace and large-scale recruitment. This is where automated AI screening comes in handy since it presents a solution to the current hiring challenges.

AI Screening – The Modern Solution

AI screening is revolutionizing recruitment by using artificial intelligence to pre-qualify candidates faster and more effectively, at a larger scale. Compared to the conventional approaches, AI screening tools offer the aspect of automation and better analysis for recruiters to engage in other productive tasks.

Now, let’s see what we mean by AI screening and some of the types of AI solutions that are changing the recruiting game, such as PreScreen AI bot for interviews.

What is AI Screening?

AI screening can be defined as the process where artificial intelligence technologies are applied to filter candidates. It operates as an alternative or additional step to the often time-consuming process of reviewing applications manually while having the ability to filter through a large number of candidates, evaluate their suitability in relation to predetermined criteria for hire, and deliver valuable information to the hiring teams.

Phone Screening vs AI Screening: Key Comparisons

To determine whether phone screening or AI screening is the right choice for your organization, it’s essential to compare them across key dimensions: speed, scalability, cost-effectiveness, candidate experience, and the quality of screening. Each method has distinct advantages and trade-offs, making the choice dependent on your recruitment needs and goals.

Speed and Efficiency

Phone Screening: Phone screening is time-intensive, as each interview requires scheduling, preparation, and active participation from both parties. A recruiter typically handles 6–8 interviews daily, which limits the speed of processing a high number of candidates. Example: A company with 200 applicants may need weeks to screen everyone through phone calls.

AI Screening: AI tools are significantly faster, capable of screening hundreds of candidates simultaneously. Solutions like PreScreen AI engage candidates in real-time and provide immediate summaries, shortening the screening process to hours instead of days. Example: PreScreen AI can complete 200 interviews in parallel within a single day.

Winner: AI Screening for high-volume hiring.

Scalability

Phone Screening: Scalability is a challenge in traditional phone screening. The number of candidates screened is limited by recruiter availability, making it difficult to scale up during hiring surges. Example: If the number of applicants doubles, the team size must also double to maintain timelines, increasing costs.

AI Screening: AI screening is highly scalable. Chatbots, video analysis tools, and AI interview bots can handle any number of candidates without additional human resources. PreScreen AI, for instance, can adapt seamlessly to fluctuating applicant volumes. Example: AI tools maintain the same efficiency whether screening 100 or 10,000 candidates.

Winner: AI Screening for adaptability in high-volume scenarios.

Cost-Effectiveness

Phone Screening: Phone screening incurs recurring costs tied to recruiter hours, telecommunications, and infrastructure. While effective for small-scale hiring, the cost per hire rises significantly in high-volume or global recruitment scenarios. Example: A recruiter earning $30/hour spending 30 minutes per screening will cost $15 per candidate.

AI Screening: AI tools have upfront costs for implementation and ongoing expenses for software maintenance and licensing. However, these costs are offset by significant savings in recruiter time and the ability to screen large volumes of candidates without additional expenses. Example: PreScreen AI reduces per-candidate costs by automating repetitive tasks.

Winner: AI Screening for long-term cost savings.
