Role guide

Prepare for your Chief Operating Officer interview

Updated 7 August 2026

A Chief Operating Officer oversees day-to-day operational and administrative functions and puts company strategy into practice through daily operations. This guide helps you prepare evidence for that remit and, because the evidence does not establish a standard interview sequence, keeps the Welsh Revenue Authority material clearly limited to the stated requirements of that specific role.

01

How the interview usually works

The supplied evidence does not establish a standard Chief Operating Officer interview sequence, format, participants or timing. The example below is limited to the stated requirements of the Welsh Revenue Authority role and should not be read as a confirmed interview stage.

  1. Welsh Revenue Authority role-specific preparation example

    The supplied evidence does not specify an interview format.

    Depends on the employer

    The Welsh Revenue Authority Chief Operating Officer role requires strategic leadership, delivery of complex and important projects, data-informed long-term decision making, change management and people leadership. The evidence does not state how or whether these requirements feature in the interview process.

    What they assess

    • The supplied evidence does not identify confirmed interview assessment criteria.

    How to prepare

    • Choose a truthful example of strategic leadership in a complex and important delivery project.
    • Prepare an example showing how you used data to reach a long-term decision and judge whether an approach succeeded.
    • Select an example of managing change while supporting people, continuous learning and operational-capability development.
    • Practise explaining each example concisely: context, decision, action, evidence and result.
02

Your preparation plan

Start with the job description and map each stated requirement to one strong, truthful example. For a Chief Operating Officer role, make the connection between strategy and daily operations clear: explain the decision, how implementation worked and what changed.

For the Welsh Revenue Authority role specifically, prepare separate examples covering complex delivery, data-informed long-term decisions and leading people through change. Keep enough detail to show your judgement without giving a long chronology.

The week before

  • Review the job description and mark every responsibility or selection criterion.
  • Build a short evidence map linking each criterion to one primary example and one reserve example.

The day before

  • Confirm the time, location, named contact and any materials you are permitted to bring.
  • If your interview is remote, test your camera, microphone, connection and meeting link.

On the day

  • Bring permitted notes with brief prompts rather than full scripted answers.

Questions to ask them

“Which operational outcomes need the most attention in the first year, and how will you measure progress?”

This clarifies the employer's immediate priorities and gives you concrete criteria for evaluating the remit.

“How do the Chief Executive Officer and Chief Operating Officer divide decisions and work together?”

Chief Operating Officer roles commonly require close collaboration with the Chief Executive Officer, so the answer can reveal whether responsibilities and decision rights are clear.

“Where does company strategy currently become difficult to put into daily practice?”

A Chief Operating Officer commonly puts company strategy into practice through daily operations; this question identifies the obstacles you would inherit.

“Which operational changes would the incoming Chief Operating Officer inherit?”

This helps you examine the scope of the work, its current ownership and the support available.

“How does the leadership team want the company culture to develop?”

A Chief Operating Officer may help develop a culture aligned with the company's mission and vision, so this clarifies what the employer expects from its operational leadership.

“Which decisions would the Chief Operating Officer own, and which would go to the board or wider executive team?”

This clarifies your authority and the points at which other senior stakeholders become involved.

06

On the day

In person

  • Bring permitted notes containing short prompts for your strongest examples rather than scripted answers.
  • Recheck the location, arrival instructions and named contact before travelling.
  • Listen to the precise scope of each question. Distinguish your decisions from work delivered by the wider leadership team.
  • Use accurate figures. If information is sensitive, explain what you can without inventing or disclosing restricted details.

Remote

  • If your interview is remote, test your camera, microphone, connection and meeting link beforehand.
  • If your interview is remote, keep permitted notes beside the screen and use them only as brief prompts.
  • If your interview is remote, choose a quiet setting and keep the named contact's details available in case the connection fails.
07

Common mistakes

Giving a generic account of the Chief Operating Officer role without connecting it to the organisation.

Chief Operating Officer interview candidates should research the company-specific remit and connect their evidence to the duties in that post.

Claiming that a process improved without explaining how effectiveness was measured.

Chief Operating Officer interview candidates are assessed on their use of key performance indexes when measuring work-process effectiveness, so identify the measure, starting point and result.

Explaining a failed process without showing how you would reconsider the strategy.

Chief Operating Officer interview candidates should show what evidence revealed that the process was ineffective, what they learnt about the strategy and how they changed course.

Describing a pressured decision as instinct alone.

Critical decisions under pressure are a recurring theme for Chief Operating Officer interview candidates; explain your analysis, risk assessment, decision and its impact.

Leaving your ability to work within the company culture unexplained.

Chief Operating Officer candidates may have their likely performance and ability to integrate into company culture assessed by Chief Executive Officers, board members and other C-suite executives. Choose evidence that shows how you worked constructively with senior colleagues.

Using poorly tailored application material or overlooking avoidable errors.

Job applicants, including Chief Operating Officer candidates, should tailor their application to the post, proofread it and obtain a fresh review.

08

After the interview

Send a brief note thanking the interviewers for their time. Refer to one specific point discussed and correct any factual detail you left unclear, but keep the message concise.
