These are the things employers ask for when they advertise this role, ranked by how often they ask. Measured across 282 distinct UK customer service adverts, collapsed from 410 postings.
What governs this role
Customer service has a published occupational standard, which is more than most of the roles in this library get. Customer service practitioner, ST0072 at level 2, sets out the knowledge, skills and behaviours an apprentice is assessed against, and it is approved for delivery by Skills England. Seven requirements here carry it. The useful part is where it and the adverts agree: the standard names dealing with customer conflict and challenge as a skill in its own right, and names right first time as a behaviour, which is the same thing the adverts call first contact resolution.

How we build this

- We verified against official frameworks where one exists, reading the live source rather than quoting from memory.
- Every percentage on this page links back to what produced it.
Important. These are not leaked interview questions. They are built from real UK job adverts and official employer frameworks, to reflect the requirements employers consistently assess.
What this sample cannot tell you. Advisor and assistant roles dominate this corpus, so it describes the front line rather than team leader or customer experience manager posts. Sector is not separated, and it matters here: vulnerable customers is named in one advert in fifteen overall and clusters almost entirely in utilities, finance and health. Check the advert in front of you rather than the average.
We do not claim these are the exact questions you will be asked. We measure what UK employers consistently ask for in their job adverts, check it against published assessment frameworks where one exists, and turn those requirements into realistic interview questions. Every question shows where it came from.
