Generally, the NHS does not require staff members to speak a foreign language fluently. However, there are some NHS Band 7 radiographer jobs on the Indeed UK website that prefer their candidates to speak a foreign language based on the geographical location of the job. The interviewers ask this question to see if you speak any foreign languages fluently to determine if you meet their preferred requirements. Describe what languages you speak and your fluency level. If you are taking language courses and are not quite yet fluent, explain how close you are to speaking fluently.
