Interview Outsourcing: How 500+ Companies Stopped Wasting Engineering Hours on Interviews

Your best engineers are spending 20% of their time interviewing candidates. That’s one full day every single week they aren’t shipping product, fixing bugs, or mentoring junior developers. For a team of ten senior engineers, you’re losing an entire year’s worth of two full-time developers just to the hiring process. Think about what your team could build with that time back.

This isn’t a minor inconvenience; it’s a massive, hidden tax on your product velocity. The pressure to hire faster has never been greater, but the traditional approach of pulling your top performers into endless interview loops creates a vicious cycle. The more you need to grow, the slower your core team becomes. We’ve analyzed data from over 400,000 interviews, and the pattern is undeniable: companies that rely solely on internal interviews face slower hiring cycles, inconsistent evaluation, and a burnt-out engineering team.

This is why hundreds of the world’s fastest-growing tech companies are turning to interview outsourcing. It’s a model that gives you access to a global network of vetted, expert interviewers on-demand. BarRaiser pioneered this Interview-as-a-Service (IaaS) category, having conducted 400,000+ structured interviews for over 500 companies. We help you reclaim thousands of engineering hours while actually raising your hiring bar.

What Is Interview Outsourcing and Why Does It Matter Now?

According to SHRM Talent Acquisition, interview outsourcing is the practice of partnering with a third-party provider to conduct technical and functional interviews on your behalf. Instead of your engineers running the interviews, you use a network of pre-vetted domain experts who follow a structured, calibrated process. This isn’t about replacing your hiring managers; it’s about supercharging them with expert-led, unbiased evaluations so they can focus on the final decision.

The reason this matters so much right now is speed and quality. The market for top tech talent is incredibly competitive, and a slow, inconsistent process means you lose the best candidates to your competitors. An engineer who has a great experience and gets a quick decision is far more likely to accept your offer. We’ve seen it time and again: a simplifyd process directly impacts offer acceptance rates. It’s no longer just about finding talent; it’s about creating an efficient, professional, and scalable engine to evaluate and close that talent before someone else does.

How Much Do In-House Interviews Really Cost?

The true cost of in-house interviews is dangerously hidden within your engineering payroll, making it easy to ignore. A senior engineer’s fully-loaded cost to the company can be anywhere from $100 to $200 per hour. If that engineer spends just 10 hours a week on hiring tasks like prep, interviews, and feedback, you’re spending between $52,000 and $104,000 per year on a single engineer’s interviewing time. Now multiply that across every senior team member involved in hiring.

Let’s make it concrete. A team of 20 engineers involved in hiring might collectively spend 100 hours a week on interviews. At an average loaded cost of $150/hour, that’s $15,000 per week, or $780,000 per year, that isn’t going toward building your product. This doesn’t even account for the cost of a bad hire, which the Society for Human Resource Management (SHRM) estimates can be up to five times the employee’s annual salary.

Interview outsourcing shifts this unpredictable, hidden expense to a transparent, per-interview cost. You pay only for the interviews you need, turning a massive capital expense into a predictable operational one.

How Does BarRaiser’s Interview Outsourcing Process Work?

The BarRaiser Interview as a Service process is designed for simplicity and speed, getting you from candidate submission to a detailed scorecard in under two days. Once your team identifies a promising candidate, you simply add them to the BarRaiser system. From there, we take over the heavy lifting. Our platform handles all the scheduling logistics with the candidate, finding a time that works across any time zone, often within hours.

The candidate then meets with one of our 4,000+ vetted domain experts for a structured, role-specific interview. Every interview is recorded and analyzed by our AI co-pilot to ensure consistency and fairness. Within 120 minutes of the interview’s completion, your hiring manager receives a detailed scorecard with a clear hire/no-hire recommendation, comprehensive notes, and key signals. Your team gets all the data they need to make a confident decision without ever having to spend an hour in a first-round technical screen themselves.

What Are the Real Benefits of Outsourcing Interviews with BarRaiser?

The primary benefit of outsourcing interviews with BarRaiser is reclaiming thousands of productive engineering hours. For example, a leading AI infrastructure company used BarRaiser to conduct over 38,000 interviews, saving an estimated 57,000 engineering hours. Another global data analytics leader saved over 4,000 hours. This is time your team can reinvest directly into your product roadmap. But the benefits don’t stop there.

You’ll also see a dramatic improvement in the quality and consistency of your hires. Our structured interview process and expert interviewers ensure every candidate is measured against the same calibrated bar. This is why our clients see a 70% recommendation-to-selection conversion rate, meaning seven out of ten candidates we recommend get hired. Furthermore, the candidate experience improves significantly. With professional scheduling and expert interviewers, candidates feel respected, leading to a 4.5+ satisfaction rating from over 100,000 reviews and a stronger employer brand.

How to Get Started with Interview Outsourcing

Getting started with interview outsourcing is a straightforward process that begins with a simple conversation. The first step is to schedule a demo with our team. We’ll walk you through the BarRaiser platform and discuss your specific hiring needs, roles, and technical requirements. We don’t believe in a one-size-fits-all approach; we want to understand your current process and where the bottlenecks are.

From there, we’ll run a calibration session. We work with your engineering leaders to deeply understand your technical bar, cultural values, and what a great hire looks like for your team. This ensures our expert interviewers are perfectly aligned with your standards from day one. You can then start with a small pilot program for a specific role or team to see the results firsthand. You’ll be amazed at how quickly you can get detailed, high-quality feedback without disrupting your team’s focus. It’s time to let your engineers be engineers again.
