Learning how to hire a Controller well starts with recognizing what most interview processes test. Technical competence is straightforward to verify. A resume shows the certifications, the systems experience, and the industry background. What’s much harder to assess in a handful of interviews is whether someone has the judgment, communication skills, and backbone to run a finance function under real pressure. That gap is exactly where most Controller hires go wrong.

Technical Competence Is the Part Most Companies Get Right

Companies are generally good at screening for technical qualifications. Does the candidate have a CPA. Have they closed the books in the relevant ERP system. Do they understand the technical accounting issues specific to the industry, such as revenue recognition for a SaaS company or percentage-of-completion accounting for a construction firm. These are legitimate, necessary filters, and most hiring processes handle them reasonably well.

The problem is that technical competence predicts whether someone can do the job on paper. It says very little about whether they’ll actually do it well once they’re managing a team, sitting across from a CFO who disagrees with them, or delivering a close that’s going to disappoint the board.

What Actually Separates a Good Controller From a Great One

A great Controller does more than produce accurate numbers on time. They exercise judgment about which issues deserve escalation and which don’t. They communicate clearly with people outside of finance, including operators, sales leaders, and board members, who don’t share their technical vocabulary. They’re also willing to deliver an uncomfortable answer to a CEO or CFO when the numbers say something leadership doesn’t want to hear.

That last trait is the one most interview processes fail to test entirely. A Controller who agrees with everything and never pushes back might be pleasant to work with, but they’re not protecting the organization from the kind of reporting or control failures that eventually become expensive problems.

The Interview Questions Most Companies Forget to Ask

Standard Controller interviews tend to ask about technical scenarios: how would you handle this revenue recognition question, walk me through your month-end close process, describe your experience with an ERP migration. Those are worth asking, but they only test knowledge.

The questions that truly reveal how a candidate will perform under pressure look different. Ask a candidate to describe a specific time they had to tell a CEO or CFO something the leader didn’t want to hear, and what happened next. Ask how they’ve handled a direct report who was making mistakes that affected the close, not hypothetically, but with a real example and a real outcome. Ask what they did the last time they discovered an error after financials had already gone out the door. Ask them to describe a disagreement with someone outside of finance, such as a sales leader pushing back on a revenue recognition treatment, and how they resolved it.

The specificity matters. A candidate who can only speak in generalities about “communicating proactively” or “building strong relationships” hasn’t necessarily done the work. A candidate who can walk through a real, specific situation, including what went wrong and what they’d do differently, is showing you actual judgment rather than an interview-ready answer.

What to Look for Beyond the Interview Itself

References are underused in Controller hiring. Most reference checks confirm dates of employment and confirm the candidate didn’t get fired. A more useful reference conversation asks the former manager or CFO directly: would you rehire this person into a more senior role, and what did you have to manage around when they were in the seat. That second question tends to surface real information that the interview process alone won’t.

It’s also worth paying attention to how a candidate talks about their previous organization’s problems. Someone who can describe what wasn’t working, what they tried to fix, and what they didn’t have the authority to fix is showing self-awareness. Someone who describes every previous employer as dysfunctional, with no acknowledgment of their own role in navigating it, is a signal worth taking seriously.

Should You Run This Search Yourself or Use an Executive Search Firm?

Companies with an internal HR function experienced in finance hiring, a clear sense of what the role needs to accomplish, and time to run a thorough process can and do hire Controllers successfully on their own. The tradeoff is usually depth of candidate access and the ability to properly vet judgment and cultural fit at the pace a business needs.

An executive search firm that specializes specifically in finance and accounting leadership brings a different kind of value: a network built for these roles rather than a generalist recruiter’s broader pool, and the pattern recognition that comes from having run this same evaluation dozens of times across different industries and company stages. The right call generally depends on how much internal bandwidth exists to run a rigorous process and how quickly the organization needs the role filled without cutting corners on evaluation.

Alliance’s executive search team places Controllers and finance leadership specifically, which means the evaluation described above isn’t theoretical. It’s the actual framework used to assess whether a candidate is ready for the role in front of them, not just qualified for it on paper.

Key Takeaway: Learning how to hire a Controller well means evaluating judgment, communication, and the willingness to push back, not just technical qualifications, and the interview questions that reveal those traits are usually the ones most companies forget to ask.

Frequently Asked Questions About What to Look for When Hiring a Controller

What should you actually look for when hiring a Controller?
Technical qualifications like a CPA and relevant ERP experience matter, but the traits that separate a good Controller from a great one are judgment under pressure, clear communication with non-finance stakeholders, and the willingness to deliver an uncomfortable answer to leadership when the numbers require it.

What interview questions actually reveal how a Controller candidate will perform?
Questions asking for specific, real examples work best: a time they had to tell a CEO or CFO something the leader didn’t want to hear, how they handled a direct report’s performance issue during a close, or how they resolved a disagreement with someone outside of finance.

Should we use an executive search firm to hire a Controller, or can we do it ourselves?
It depends on internal bandwidth and finance hiring experience. A specialized executive search firm brings deeper candidate access and pattern recognition from running similar searches repeatedly, while an internal process can work well for companies with the time and expertise to run it thoroughly.
