NHS STP Interview Questions: Example Themes and How to Answer

Independent guidance. PathologyLabTraining is not affiliated with or endorsed by the NHS or NSHCS. The official questions, format and timetable change each cycle, so always confirm details at nshcs.hee.nhs.uk.

STP direct entry interviews are held virtually, typically via Microsoft Teams, and run up to around 50 minutes with a panel that includes at least one scientist. Questions cover general science, specialist science, and values and behaviours. The examples below are original illustrations only. They are not real or secure questions, and no website can give you those.

Before the questions begin

Interviews usually open with a short, unscored chance to explain your interest in the STP. Treat this as a clear, 60 second summary of your motivation rather than a rehearsed speech. Then the scored questions follow, with roughly four minutes to answer each and possible follow ups.

Specialist science themes

These test the depth behind your chosen specialty. Strong answers use accurate terminology and show you understand the clinical purpose of what you describe.

Example style prompts to practise with:

• Explain a technique or analyser used in your specialty and what its results tell the clinical team.
• Describe a source of error in a common test and how a laboratory controls for it.

To answer well, define the concept briefly, explain the mechanism, then connect it to patient impact. Do not bluff. If you are unsure, reason aloud and stay honest.

General science themes

These check broader scientific literacy and reasoning. A strong answer is structured and shows you can think, not just recall.

Example style prompts to practise with:

• How would you explain quality control to a non scientist colleague?
• What does a result outside the reference range tell you, and what would you check next?

Answer by stating a clear principle, giving an example, and noting a limitation or caveat. That structure signals scientific maturity.

Values and behaviours: use STAR

Values questions explore how you work with others, handle pressure, and uphold professional standards. Use the STAR structure to keep examples concrete:

• Situation: set the scene briefly.
• Task: what was required of you.
• Action: what you specifically did.
• Result: the outcome and what you learned.

Example style prompts to practise with:

• Describe a time you handled a disagreement within a team.
• Tell us about a time you spotted a mistake. What did you do?

Choose real examples where your own action is clear. Panels can tell the difference between a genuine story and a generic one.

Practical preparation

Re read the job description and person specification, review your own application, and prepare two or three questions for the panel. Join early and have photographic ID ready. Note that AI use is not permitted during the interview itself, so your preparation has to be internalised.
