The questions to expect
Tell me about a complaint you investigated end-to-end. How did you establish what actually happened?
Show evidence habits: pulled the records, listened to the calls, heard both sides, separated fact from feeling — then decided and could defend it.
Talk me through a complaints process you've worked under — timescales, escalation, and where the Financial Ombudsman or an equivalent scheme comes in.
Know the shape: acknowledgement, investigation, final response within the regulated window, and the customer's onward rights. Regulated firms will expect the vocabulary.
Describe telling a customer their complaint was not upheld. How did you deliver it?
Not-upheld done well: empathy up front, the reasons in plain English, their next options explained. The customer should feel heard even while hearing no.
The customer is right, and fixing it properly will cost the business real money. Walk me through your decision.
Fairness first is the only defensible line: put it right, within your authority or escalated with a recommendation — and show you'd flag the root cause too.
Tell me about a final-response letter you're proud of. What made it clear, fair and final?
Good letters answer every point raised, in the customer's language, with the decision and reasons unmissable. Bring the structure you use.
A complainant is vulnerable — recently bereaved, struggling financially — and demanding compensation you can't justify. How do you handle it?
Two duties at once: extra care in how you treat them (time, tone, signposting support) without bending the outcome beyond what's fair. Show you can hold both.
Tell me about spotting a systemic issue from a pattern in complaints.
Root-cause thinking is what separates handlers from processors: the pattern you noticed, who you told, and what changed so those complaints stopped.
Complaints work is difficult conversations all day. Why do you want it?
The believable answer: you like fixing things properly and being trusted with judgement — with a story of a wrong you enjoyed putting right.
AI can draft complaint responses and spot trends across thousands of cases. Where does it help, and what must stay with the human?2026
Let it find patterns and draft structure; keep the human owning the investigation, the judgement and the final letter — every fact and every tone choice checked.
Tell me about a time you turned an angry customer around.
The pivot moment is the story: what you said after listening that changed the temperature. End with how the customer left the interaction.
How do you handle a customer you genuinely cannot help — when the answer really is no?
A good no has three parts: empathy first, the clear reason, then what you CAN do — an alternative, an escalation route, a next step.
A customer is rambling and your queue is building. How do you take control of the conversation politely?
Name the technique: summarise what you've heard, ask a closed question, signpost the next step. Control without rudeness is a learnable craft — show you've learned it.
