The interview

The main stage of your application to ST3 is the interview. Here you will be asked a series of questions by clinicians at different interview stations, and will have your documentation verified and assessed to confirm your eligibility, and the validity of achievements in your application checked.

Time required at interview

The exact timings can vary slightly by interview centre but typically this will involve the following:

  • Arrival  - most centres set the interview slot times that you book 30 minutes before you interview is planned to begin. This time is used to register your arrival and check your eligibility documents.
  • Interview  - for most specialties, the time allocated to each of the three stations is 10 minutes, with five minutes' transfer time in between. Thus the total interview time will be approximately 45 minutes. For allergy, immunology, cardiology and clinical  pharmacology & therapeutics, the time allocated for each station is 15 minutes; the approximate total interview time will be one hour.
  • After interview  - this can vary by interview centre but usually you will be free to go as soon as your interview ends. In some cases the clinical lead may need to speak to a candidate to clarify something from the interview but this is not usual.
  • Total time  - the advice is that you should expect to spend about two hours at the interview centre. In most cases this will be less but the schedule can often over-run. This is just a rough guide and it cannot be guaranteed that all candidates will be able to leave within two hours of their arrival time so please bear this in mind when planning your transport etc.

Consistent across UK

The structure and content of ST3 interviews will be consistent within each specialty; that is, where multiple regions are used for a specialty, the makeup of the interview will be exactly the same.

Whilst very similar, there is variation between specialties in the format and question areas.  However, one of the three stations will always assess your evidence and your suitability for the specialty.  For specialty specific interview content please refer to each  specialty's  page.


Certain specialties require you to prepare a presentation prior to the day and therefore it is very important to check whether or not this applies to you.


All stations will be staffed by two consultant interviewers, each of whom will award you a mark on each of two aspects assessed in that station. This means that you will be assessed and scored by six different inteviewers and given 12 individual marks.

In some cases a third clinician at station 1 may be present to assist with the checking/review of your documentation and the application; however, you will only be marked by the two asking questions.

Lay representatives

Lay representatives will be used to monitor ST3 interviews. They will not be involved in candidate assessment; their role is to assist in the quality assurance of the interview process. 

They will observe a selection of interviews so you may or may not see one during your interview.
