Start with the vacancy
Read the job description, person specification and invitation together. For each criterion, choose a truthful example from your work, study or volunteering. Note the situation, your responsibility, what you did, the result and what you learnt. Be clear about which decisions were yours and which belonged to a supervisor or the wider team.
UK Research Assistant applicants need working knowledge of the research methods relevant to the advertised project. Review every method named in the vacancy and prepare to explain where you used it, how much responsibility you had and what limits or uncertainty affected the work.
Do the same for any software, equipment or other tools listed by the employer. Mention only tools you have genuinely used. For each one, write down the task, what you did and how independently you worked. If you have a gap, be ready to describe the closest relevant experience without pretending the gap does not exist.
Choose several examples so that every answer does not return to the same project. You might use one about handling records or data carefully and another about a problem, a deadline or explaining research to someone else. Brief prompts can help you remember the details, but practise answering aloud in your own words.
Prepare for the format in your invitation
For UK Research Assistant applicants, a practical exercise or presentation depends on the employer; it is not part of every hiring process. Follow your invitation and person specification. If they include a presentation or task, check the brief, audience, time limit and assessment criteria, then rehearse the complete response within that limit. Ask the named contact about anything unclear.
If you have to present, make the main point easy to follow and cut material that does not answer the brief. Practise aloud and prepare for questions about your choices. For a remote interview, test the joining link, camera, microphone and screen sharing beforehand.
