Managing High Application Volumes

According to Upwork's 2025 In-Demand Skills report, there's been a staggering 220% annual growth in AI-related skills. While this reflects the increasing demand for AI expertise, it also creates major challenges for businesses trying to find qualified AI engineers [2]. Let’s break down some of the key obstacles, including resource demands and skill verification.

Screening Time and Resource Costs

When application volumes spike, hiring teams often face delays and resource strain. Traditional screening methods struggle to keep up, especially as more candidates use AI tools to enhance their applications, making it difficult to assess actual performance.

The financial impact of screening becomes clear when you factor in the cost of tools and platforms:

Aside from the resource drain, another major hurdle is ensuring candidates possess the technical skills they claim to have.

Skill Verification Challenges

Verifying technical skills is a pressing issue beyond just handling application volume. Research shows that only 25% of employees can effectively work with AI solutions, and just 19% can proactively use AI to solve problems [2]. This gap between claimed and actual abilities highlights the need for more effective verification processes.

Here are some methods companies can use to evaluate AI talent more thoroughly:

Adding to these challenges is the issue of unconscious bias in screening. Studies reveal that resumes with White-associated names are 85% more likely to advance to the next hiring stage, compared to just 9% for resumes with Black-associated names [3]. This highlights the need for fair and unbiased evaluation practices.

Technical Assessment Limitations

Evaluating the technical abilities of AI engineers on Upwork comes with its own set of challenges, especially when it comes to understanding their practical problem-solving skills.

Unverified Skill Claims

The rise of generative AI has made traditional methods of verifying skills less reliable. Testing has shown that every bidder on Upwork used Large Language Models (LLMs) to answer screening questions, and all responses were incorrect [1].

"If you are using sort of the standard screening approaches or you are relying on the veracity of profiles or the messages sent to you to, for example, determine hiring potential, then you need to completely reevaluate your methodology, because we basically just determined that 100 percent of people are attempting to use these tools right now, which means that you're no longer measuring their performance, you're measuring performance of these models." – Eli-Shaoul Khedouri, founder and CEO at Intuition Machines [1]

Recent data highlights this shift:

These trends underscore the growing difficulty of assessing skills effectively, leading to further challenges in evaluating practical expertise.

Technical Evaluation Challenges

Beyond verifying skills, assessing an individual's ability to solve real-world problems is a persistent issue. For instance, even advanced AI models like Claude 3.5 Sonnet have managed to solve only 26.2% of problems, highlighting the difficulty of evaluating a deep understanding of integrated systems [4].

To navigate these challenges, companies can implement a more structured technical assessment framework:

This type of structured approach can help address some of the difficulties in evaluating technical capabilities effectively.

Direct and Indirect Hiring Expenses

Hiring AI engineers on Upwork involves more than just paying hourly rates or project fees. To plan your budget effectively, you need to consider additional costs that can add up quickly.

Platform Fees and Charges

Upwork applies a Client Marketplace Fee of up to 7.99% on all payments made to freelancers [5][6]. This fee is consistent across various payment methods:

Freelancers and agencies also pay a 10% service fee on their earnings [7]. This fee is often built into their rates, which can increase the overall cost for businesses. On top of these fees, there are operational costs that aren't immediately obvious but can impact your budget.

Resource Investment and Growth Limits

Beyond direct fees, the hiring process itself can drain resources. For example, about 30% of proposals are fake, 30% are irrelevant, and 30% are AI-generated, leaving only 10% of applications as genuinely qualified [8]. This means businesses must invest significant time and effort to find the right talent.

Other hidden costs to consider include:

• HR review time and interviewer resources: Screening and interviewing candidates take time and manpower.

• Administrative expenses: Setting up payroll and onboarding new hires adds to your costs.

• Productivity losses: New hires often require time to get up to speed, which can temporarily slow down project progress [9].

Hourly rates for AI engineers on Upwork range from $5 to over $130 per hour [7]. This wide range, combined with unpredictable availability and the need for thorough quality checks, makes managing budgets and scaling projects more challenging.

Better Ways to Hire AI Engineers

To address the challenges of hiring through platforms like Upwork, these approaches provide clear alternatives and measurable improvements.

Working with AI Recruitment Experts

Hiring skilled AI engineers requires thorough vetting by professionals. Since most AI work (about 90%) involves software development, recruiters must ensure candidates have a strong programming background [11].

"Finding elite Generative AI talent requires a hiring strategy that goes beyond resumes. Every candidate undergoes rigorous vetting to ensure they bring the expertise, adaptability, and strategic thinking needed to drive AI-powered innovation." - Overture Partners [10]
