Your best engineers are spending 15 hours a week interviewing candidates. That’s nearly two full days not shipping product, fixing bugs, or mentoring junior developers. When you’re facing the challenge of hiring at scale, this isn’t just a bottleneck; it’s a multi-million dollar productivity leak. We’ve seen it play out across the 400,000+ technical interviews BarRaiser has conducted for over 500 companies. The math is brutal, but the solution is surprisingly simple.

The pressure to grow your engineering team by 100, 200, or even 500 people in a few quarters is immense. You’re trying to build the plane while flying it, but your pilots are stuck in the terminal screening new crew members. This frantic pace of in-house interviewing leads to inconsistent evaluations, interviewer fatigue, and a terrible candidate experience. Your hiring bar starts to slip, and your best people get burned out doing a job they weren’t hired for.

This is where a new model called Interview-as-a-Service (IaaS) comes in. It’s about outsourcing your technical rounds to a global network of trained, calibrated experts. BarRaiser pioneered this approach, saving one leading AI infrastructure company over 57,000 engineering hours and helping them make 5,500+ hires in just two years. Your team gets their time back, and your hiring process gets faster, fairer, and more consistent.

What Is Hiring At Scale and Why Does It Matter?

According to SHRM Talent Acquisition, hiring at scale is the process of rapidly and efficiently recruiting a large number of employees without sacrificing quality or overwhelming your internal teams. It’s not just about posting more jobs; it’s a strategic shift in your talent acquisition function to handle high volume. This matters because for growth-stage companies, the ability to scale the engineering team directly dictates the ability to scale the product and revenue. Slow hiring means delayed roadmaps, missed market opportunities, and a direct hit to your bottom line. The uncomfortable truth is that most traditional, in-house interview processes are built for hiring 10 people a quarter, not 100. They break completely under the pressure of true scale, leading to chaos and bad hires.

How Does BarRaiser Make Hiring At Scale Possible?

BarRaiser makes hiring at scale possible by replacing your internal interview bottleneck with an on-demand, global network of 4,000+ expert interviewers. Instead of your engineers clearing their calendars, you simply upload candidates to BarRaiser. We handle the scheduling and conduct structured, in-depth technical interviews 24/7 across any time zone. Every interview is recorded and assessed against a calibrated rubric, ensuring consistency no matter who conducts it. You get a detailed scorecard and recommendation delivered within 120 minutes of the interview’s completion. This transforms your hiring engine from a slow, manual process into a simplifyd, automated one that can handle hundreds or even thousands of candidates a month without burning out a single engineer.

What Are the Real Benefits of Hiring At Scale with BarRaiser?

The real benefits are speed, quality, and massive cost savings. Companies that use BarRaiser see a 70% recommendation-to-selection conversion rate, which means seven out of ten candidates we recommend get hired. This isn’t just about filling seats; it’s about raising the talent bar. For example, a global data analytics leader saved over 4,000 engineering hours by outsourcing 2,000+ interviews to us, which is the equivalent of two full-time senior engineers’ salaries for a year. The speed is another huge factor. Our end-to-end process from candidate upload to scorecard delivery takes less than two days, not the weeks it takes most companies. This speed and a positive experience, reflected in our 4.5+ rating from over 100,000 candidate reviews, dramatically improves offer acceptance rates.

How Much Does Hiring At Scale Cost?

The true cost of hiring at scale isn’t the recruiter’s salary; it’s the hidden cost of your engineering team’s time. A senior engineer with a loaded cost of $100 per hour who spends 10 hours a week on interviews is costing you $1,000 a week, or over $50,000 a year, just on interviewing. Multiply that by the 10-15 engineers on your hiring panels, and you’re spending half a million dollars in engineering time that could have gone into product development. BarRaiser replaces that massive, hidden operational expense with a transparent, predictable per-interview price. You only pay for the interviews you conduct, turning a fixed, hidden cost into a variable, managed one. It’s not about spending more; it’s about reallocating your most valuable resource, engineer-hours, back to where it belongs: building your product.

What Should You Look for in an Interview Outsourcing Provider?

You should look for a provider with a deep bench of genuine experts, a commitment to structured interviewing, and proven results at scale. Don’t settle for a platform that just connects you with gig-economy interviewers. Ask about their vetting and training process for interviewers. At BarRaiser, our 4,000+ experts are practicing senior engineers and architects from top product companies. Next, ensure they use a structured methodology. According to SHRM, structured interviews are significantly more predictive of job performance. We’ve built our entire system on this principle. Finally, look for proof. Ask for data on conversion rates, hours saved, and candidate satisfaction. Any credible partner should be able to share anonymized case studies and concrete metrics from their 400,000+ interviews.

How Do You Get Started with Hiring At Scale?

Getting started is a simple, three-step process that you can begin today. First, do a quick audit of your current process. Calculate how many hours your engineering team spent on interviews last month and multiply that by their average hourly cost. This gives you your “hidden interview cost.” Second, identify the one or two roles that are your biggest hiring bottlenecks right now. You don’t have to switch everything at once. Start with the roles causing the most pain. Third, schedule a call with our team. We’ll walk you through a live demo of the BarRaiser platform, show you a sample scorecard, and build a plan to launch a pilot program in just a few days. You can see the results for yourself before making a bigger commitment.

Stop letting interviews steal your best engineering talent. It’s time to let your builders build. Book a demo today and see how you can hire 100+ engineers without burning out your team.
