So regarding scoring, each question is scored usually out of 5 or 10, and is scored individually by each member of the panel. I might give you 5 for an answer whereas someone else may give you 3. The scores are added up at the end and the highest score is usually offered the job.
Not necessarily scored for hitting buzz words, and people do it differently. I mark on the relevance of the example, or understanding of the question and correct answer.
For example if the question was: "what does confidentiality mean to you" and your answer was "not discussing patient details" whilst being correct, that answer might only get you a 1 (from me) however an answer closer to 5 might be something along the lines of "to me confidentiality is paramount in this post, I understand the importance of not sharing confidential information about patients or staff unless the individual I'm speaking to is directly involved, for example, I would not discuss a patients condition with x doctor if she was not the treating physician. I know not to discuss patients results on the phone, or discuss patient details with relatives unless given direct permission to do so from the patient. I always lock my computer screen when I leave my desk, I dispose of any confidential information appropriately by deleting or throwing paperwork away in the confidential waste bin."
I basically always look for more than once sentence answer which usually includes an example (if appropriate) of where you have demonstrated that skill.
Ie if the question was "tell me about your main strength and weakness" a poor answer would be "my strength is organisation and my weakness is I'm too much of a perfectionist"
In my opinion and experience, A better answer would be "I think my main strength is my organisational skills. I use to do lists with deadlines to prioritise my work load to ensure I achieve everything I need to do in a good time frame. This skill will be particularly beneficial in this role because of the high demands of the post and the varied duties that might be asked of me with short notice. My weakness is that I have a really high standard for myself and occasionally spend too long making sure something is perfect which can impact deadlines or cause me to focus on one area rather than another. However I am working on this by ensuring I have a clear dialogue with my managers to ensure we're on the same page as to what is the minimum standard accepted, having better time management skills and prioritising my work load whilst not compromising the quality of the work. This is something I would continue to do and improve on in this role"
Values questions tend to be something like "do you know the values of x trust" or "which value do you most identify with and why" but previous poster is right, not always asked but I would have answers prepared anyway as it's easy points to score.
Other questions to think about may be: team work, working to deadlines, tell us about a time where something didn't go quite to plan - how did you handle that, why do you want this role, what is your understanding of this role, what do you expect to be the biggest challenge in this role/that you'll personally face in this role.
Good luck all x
