A controller screening call should establish what the candidate owned: the close calendar, the audit outcome, the control environment and the team. Ask how many days their close took and what they changed, what the auditors proposed as adjustments last year, which controls failed and how they fixed them, and who they hired or managed out. Real controllers answer with numbers, findings and names of roles. Candidates stretching from assistant controller or accounting manager describe the process without saying where the decisions sat.
This guide covers controller, corporate controller and plant or division controller roles. For the people who report to them, use staff accountant phone screen questions. For CFO and VP Finance searches, where board exposure and capital decisions lead, the executive search screening questions fit better.
Which controller: company, division, plant or fractional
| Type | What the job usually is | Facts to ask for | Common overstatement |
|---|---|---|---|
| Corporate controller, private company | Owns the close, the audit or review, often payroll, AP and tax coordination; reports to a CFO or the owner | Revenue range, entity count, audit or review, team size, who does tax | "Oversaw finance" when an outside CPA firm prepared the statements |
| Corporate controller, public company | Quarterly and annual reporting, SEC filings support, SOX controls, audit committee materials | Filer status, their part in the 10-Q and 10-K, SOX program owner, external auditor | "SEC reporting" meaning they supplied schedules to a reporting team |
| PE or lender-backed controller | Monthly lender or sponsor reporting, covenant calculations, add-on acquisitions, fast close | Close days, covenant package contents, number of acquisitions integrated | "M&A integration" meaning they received the opening balance sheet |
| Division or plant controller | Cost accounting, inventory, standard costs, capex, site P&L; reports to corporate and site leadership | Costing method, inventory value, physical count process, capex approval limits | Corporate-level scope claimed for a single site |
| Fractional or outsourced controller | Several small clients, often part-time, heavy on setup and cleanup | Client count, hours per client, what they owned versus advised | Several clients presented as one deep role |
Close leadership: the calendar they own
Ask the candidate to describe the close as the person responsible for it: "Walk me through your close calendar, including what you review, what you sign off, and what you changed since you took it over." An accounting manager describes the tasks. A controller describes the sequence, the dependencies and the decisions.
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| How many business days is your close today, and what was it when you started? | "Twelve days when I arrived, seven now. Most of it came from moving accruals to a pre-close and killing a manual intercompany process." | No number, or a faster close with no explanation of how. |
| What do you personally review before the books lock? | A defined set: flux review above a threshold, high-risk reconciliations, manual entries above a limit, revenue cutoff. | "Everything," on a team of eight, or nothing specific. |
| What was the last error that got past the close, and how did it surface? | An honest example, how it was caught (auditor, analyst, customer), and the control added. | "None." Every close lets something through eventually. |
| What do you hand the CFO or owner, and what do they ask most? | A reporting package they designed and the recurring question behind it. | Cannot describe what leadership receives. |
| Which close tools do you use: BlackLine, FloQast, Numeric, or a checklist in Excel? | Names the tool and what they configured or changed in it. | A tool name with no ownership of how it is used. |
Worked example (invented numbers)
The candidate says: "I cut the close from 10 days to 5." Ask two questions:
- "What moved?" A real answer lists specific changes: accruals estimated before month-end, reconciliations split by risk, a cutoff for late invoices.
- "What did you give up?" A real answer names a trade: "Low-risk recs are quarterly now," or "We book a true-up the following month for utilities."
Halving a close without a trade-off is possible but rare. The trade-off is where you hear whether the candidate designed it.
Audits: findings, adjustments and the relationship
The last audit is the best evidence of a controller's work, because an outside firm graded it. Ask directly and write down the specifics.
- "Who is your auditor, and is it an audit or a review?" Strong: firm name and type of engagement. Red flag: unsure whether the statements are audited.
- "How many proposed adjustments did the auditors have last year, and what were the big ones?" Strong: a count or a range, the largest one, and why it happened. Red flag: "None" at a company that has just gone through a system change or an acquisition.
- "Did the auditors issue a management letter, and what was in it?" Strong: names the comments and what was done about them. Red flag: has never seen one.
- "How many PBC items were outstanding at fieldwork, and who chased them?" Strong: a system for the provided-by-client list and an owner. Red flag: auditors came back multiple times for the same items.
- "Tell me about a disagreement with the auditors on an accounting position." Strong: the position, the research, the outcome, including when they conceded. Red flag: always agreed, or treated auditors as adversaries.
Internal controls and SOX
Public companies must maintain internal control over financial reporting and have management assess it. The independent auditor attestation under Section 404(b) applies only to accelerated and large accelerated filers; the SEC's 2020 amendments excluded many smaller reporting companies with annual revenue under $100 million from those definitions, as described in the SEC's compliance guide on filer definitions (as of September 2026). So "SOX experience" means different things at different companies. Ask which.
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| Was the company subject to 404(b) auditor attestation, or management assessment only? | Knows the answer and how it changed the workload. | Does not know whether the auditor tested controls. |
| How many key controls did finance own, and who tested them? | A number, internal audit or an outside firm, and the controller's part in design versus execution. | "SOX" with no controls named. |
| Tell me about a control deficiency found on your watch. | The control, the severity (deficiency, significant deficiency, material weakness), the root cause and the remediation. | No deficiencies ever, or blames the previous controller for all of them. |
| (Private company) What controls did you put in place without a SOX requirement? | Segregation of duties in payments, journal entry approval limits, vendor master change review. | One person could add a vendor and pay it, and the candidate did not flag it. |
If the candidate worked at a public company that disclosed a material weakness, it is in the filings. Ask what their role was. A controller who led the remediation is often a stronger hire than one who never faced a finding.
Team: hiring, reviewing and letting people go
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| How many people report to you directly and indirectly, and what are their roles? | A clear org: "Two managers, six staff: GL, AP, payroll and revenue." | Counts the whole finance department, including people who report to someone else. |
| Who did you hire in the last two years, and why that person? | A specific hire and what they looked for. | Never hired; inherited everyone, for a role that must build a team. |
| Tell me about someone who was not working out. What did you do? | Expectations, documentation, support, and a decision with HR. | Waited for the person to leave, or describes it with no process. |
| How do you train a new staff accountant on your close? | Checklists, desk procedures, shadowing, a first close with review. | "They figure it out." |
Systems, complexity and scope
Controllers differ most in the complexity they have handled. Map it quickly, then compare with the client's situation.
- Entities and currencies: "How many legal entities, which currencies, and who did consolidation and eliminations?"
- Revenue: "How is revenue recognized, and what was the hardest judgment?" Subscription, multiple deliverables, percentage of completion and distributors each carry different work under ASC 606.
- Inventory and costing: "Standard or actual cost? How were variances handled, and how did the physical count go?"
- ERP: "Which system, and did you run an implementation? What was your part, and what would you do differently?" A controller who led a NetSuite or Dynamics 365 move can describe cutover, data migration and the first close after go-live.
- Tax and treasury: "Who owns tax provision, sales tax and cash management: you, the CFO or outside firms?"
- Debt: "Did you prepare covenant calculations or lender packages? Ever get close to a breach?"
CPA status and other credentials
Many controller searches list the CPA as required. The license is issued by a state board of accountancy, and a candidate may not use the title until licensed. Verify with NASBA's CPAverify or the state board's lookup. The staff accountant guide covers exam status phrases like "CPA eligible" in detail; at controller level the questions are shorter.
| Credential | What to ask | What to check |
|---|---|---|
| CPA | "Which state, is it active, and when did you get it?" | State board lookup or CPAverify; inactive and lapsed statuses exist |
| CMA | "Did you complete the experience requirement?" | The Institute of Management Accountants requires both exam parts, a bachelor's degree or an accepted professional certification, and two continuous years of management accounting or financial management experience, per its CMA certification page |
| Public accounting background | "Which firm, which level did you leave at, and which industries did you audit?" | Reference check with a former manager or partner |
| No credential | "The client prefers a CPA. How would you address that?" | Relevant for private companies that accept experience instead; confirm with the client first |
Logistics, knockout checklist and scorecard
Ask about on-site expectations during close and audit fieldwork, travel to other sites, salary expectations and bonus structure (not pay history; see salary expectation questions), notice period, which for controllers often includes finishing a close or an audit, and other processes. Ask everyone the same work authorization questions.
Must-ask on every controller screen
- Type of controller role, company size, entity count and ownership (public, private, PE-backed).
- Close length now and when they started, with what changed.
- Last audit: firm, adjustments, management letter comments.
- One control deficiency and the remediation.
- Team size, one hire and one performance problem.
- Systems and any implementation, with their role.
- CPA status checked if claimed or required.
Knock out, or flag before submitting, if:
- The client requires a licensed CPA and the license is not active or cannot be found.
- The candidate has never owned a close or been the audit's main contact, for a role that owns both.
- The candidate cannot describe a single audit adjustment, control issue or error they dealt with.
- The complexity gap is large: a single-entity service company background for a multi-entity, multi-currency role, with no plan for closing it.
| Area | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| Close leadership | Executed tasks | Reviewed parts of the close | Owned the calendar and sign-off | Redesigned the close with measured results |
| Audit | Supplied files | Handled requests | Main contact, knows adjustments and comments | Reduced adjustments and resolved positions with evidence |
| Controls | Keyword only | Performed controls | Owned controls and fixed a deficiency | Designed the control environment |
| Team | No reports | Supervised, did not hire | Hired and developed | Built and restructured a team |
| Logistics fit | Deal-breaker | Two open questions | One open question | All aligned |
Write the evidence next to each score: "Close from 12 to 7 days by moving accruals to pre-close; last audit had 3 proposed adjustments, largest on inventory reserve." Interview Signal attaches quotes like these to each score from the call itself. Before an offer, a reference check with the CFO they reported to is the best place to confirm audit results and team building.
Questions people ask
Does a controller need to be a CPA?
Not by law in most private companies, but many clients require or strongly prefer it, especially public companies and businesses with an external audit. Ask the client at intake whether it is a knockout, and if the candidate claims a license, check it with the state board or NASBA's CPAverify.
What is the difference between an assistant controller and a controller screen?
An assistant controller usually runs the close and reviews the team's work. A controller owns the result: the audit outcome, the control environment, the calendar and the people. Screen an assistant controller on execution and review, and a controller on decisions, audit findings and team building.
Is it fair to ask a controller about a material weakness at a previous company?
Yes, if the company was public, because material weaknesses are disclosed in public filings. Ask what the candidate's role was in finding and fixing it. Owning a remediation is a strength; being unable to discuss a disclosed weakness they lived through is a flag.
How long should a controller phone screen take?
Plan for 30 to 45 minutes. The close, the last audit and the team take most of it; logistics and compensation take ten minutes. Leave technical accounting depth to the CFO's interview.
