Request a walk-through of their process for identifying an unrecorded accrual.

Owners who have performed this work themselves provide specific, repeatable steps they follow to ensure accuracy when they arrive in a new environment.

What should the brief say about Strong answers versus rehearsed answers?

Rehearsed answers sound like a summary of GAAP principles or an explanation of how a department ought to function in a perfect world. A strong answer describes a specific constraint the candidate faced, such as an incomplete set of bank records or a broken payroll integration, and the exact workaround they implemented to meet the deadline.

Rehearsed answers sound like a summary of GAAP principles or an explanation of how a department ought to function in a perfect world. A strong answer describes a specific constraint the candidate faced, such as an incomplete set of bank records or a broken payroll integration, and the exact workaround they implemented to meet the deadline. They identify the limitation of their own control and show how they communicated this risk to the owner.

Look for how the candidate discusses the relationship between the trial balance and operational decisions. A rehearsed candidate discusses reporting in the abstract. An experienced interim operator links the numbers to the cash position. They describe situations where they flagged an issue to an owner based on their analysis of the ledger, regardless of whether the owner wanted to hear the bad news.

What should the brief say about Documents and work samples to discuss?

If they cannot explain a basic discrepancy between these two documents without referring to a staff member, they lack the foundational control required for an interim assignment.Discuss a past project involving the documentation of standard operating procedures for a finance function.

Ask the candidate to explain a set of internal financial statements they have produced. They should be able to point to where the cash flow report deviated from the profit and loss statement and explain why. If they cannot explain a basic discrepancy between these two documents without referring to a staff member, they lack the foundational control required for an interim assignment.

Discuss a past project involving the documentation of standard operating procedures for a finance function. An effective interim resource will bring examples of checklists or workflow charts they created to hand off to a permanent hire. These documents should be specific to the tasks that usually cause issues in a business, such as vendor onboarding, credit card reconciliation, or inventory valuation.

What should the brief say about Questions about constraints and judgment?

Pose a scenario where the company is behind on tax filings or audit preparation. The right candidate does not panic or suggest an immediate total system overhaul. They describe a process of triage, where they prioritize the most critical regulatory requirements first and communicate a realistic schedule to the stakeholders.

Pose a scenario where the company is behind on tax filings or audit preparation. The right candidate does not panic or suggest an immediate total system overhaul. They describe a process of triage, where they prioritize the most critical regulatory requirements first and communicate a realistic schedule to the stakeholders. They distinguish between work that needs immediate correction and work that can wait until the books are stabilized.

Ask how they decide when to override a system-generated report. This reveals their judgment regarding the gap between software inputs and reality. A strong controller keeps a record of these manual adjustments and explains the logic for every change made to the system output. They treat manual entries as a temporary solution to be documented, not a permanent part of their workflow.

How to handle confidential examples?

However, they should still be able to discuss the mechanics of the problem they solved. If a candidate uses confidentiality as a reason to avoid describing their own actions or technical decisions, they are likely obscuring a lack of direct experience.

Expect candidates to be vague about specific company names or proprietary financial figures if they are currently under a non-disclosure agreement. However, they should still be able to discuss the mechanics of the problem they solved. If a candidate uses confidentiality as a reason to avoid describing their own actions or technical decisions, they are likely obscuring a lack of direct experience.

Judge them on their ability to generalize a high-level problem. They should be able to say, We had a revenue recognition issue across three service lines, and here is how I reconstructed the revenue schedule. This conveys the necessary technical details while protecting the privacy of their former employer. A controller who cannot describe the technical nature of their past work while maintaining confidentiality is not a good communicator.

What should the brief say about Choosing without relying on the title?

A candidate with an impressive title from a large firm may struggle in an interim role where they must perform the data entry, account reconciliation, and board reporting themselves. The title suggests oversight, but the interim role requires a doer.

A candidate with an impressive title from a large firm may struggle in an interim role where they must perform the data entry, account reconciliation, and board reporting themselves. The title suggests oversight, but the interim role requires a doer. Focus on whether they have operated in businesses of your scale where they were the primary contact for both the ledger and the bank.

Ignore the prestige of their previous employers. Instead, prioritize candidates who have successfully stabilized finance functions in small-to-mid-sized companies with limited administrative staff. Look for a professional who has worked in the engine room of a business, not just the management office. The best interim controllers are those who treat the general ledger as their primary tool and the owner as their primary client.

What is the main difference between a Controller and a CFO?

A Controller focuses on the integrity of the ledger, monthly close processes, and tax compliance. A CFO focuses on capital strategy, banking relationships, and growth planning based on the data the Controller provides.

Should I require an interim hire to have public accounting experience?

Public accounting experience is useful for audit readiness but does not ensure the person can handle day-to-day cash management or operational accounting. You need someone who has worked in an industry setting where they were responsible for the bottom-line results.

How do I know if they can handle my specific software?

Skilled controllers adapt to new accounting systems by applying core general ledger logic rather than memorizing software features. Evaluate applicants based on their ability to articulate complex financial workflows and balance sheet reconciliation processes during the initial transition period.

No upfront fee. You pay only if you hire.

This is our standard approach to interim placements. We aim to connect you with professionals who can deliver immediate value.

How are recruiting fees agreed?

No upfront fee. You pay only if you engage someone we present. We scope the assignment before quoting; the fee page explains our model.

How soon can we see options?

Availability depends on the assignment and the people who fit it. We qualify interest and commitments rather than promising a shortlist date before the search is scoped.

What if the scope grows?

Discuss new responsibilities before adding them to the engagement. Agree the priorities and record any change to the brief and terms.

Can we extend an engagement?

Discuss what remains unfinished and whether the same responsibility is still needed. Extensions depend on the person's commitments and the agreed engagement terms.

Can the appointment become permanent?

A permanent move can be discussed if both sides want it. Review the future role and the applicable agreement instead of assuming that temporary coverage automatically converts.

How is a confidential search handled?

Tell us what can be disclosed and whom we must not contact. We agree those boundaries before approaching people; do not send sensitive records with an initial brief.

What are the replacement terms?

We offer a candidate replacement guarantee on standard search agreements. The applicable period and exact terms are set out in the signed client recruiting agreement.

What do you not do?

We do not sell job-board reposting as a search or bill hourly for recruiting work. We do not take a retainer unless expressly agreed, and an introduction does not authorize an engagement.
