Don't mind at all - the more help the better - I need it - I haven't had a proper interview in over 5 years - do you mind sharing some examples of strengths and weaknesses that you have heard that would impress an interviewer for a office based role?
To be honest the actual example given is less important to me than the way in which it’s delivered.
So, if a candidate gives an example and then talks about either its impact or how they work to mitigate it (in the case of a weakness) or build upon it (in the case of a strength), it lends credibility.
For example, someone saying that they have a tendency to be over critical of themselves, and therefore sometimes of others, is showing self-awareness and awareness of how it impacts others. If they then explain how they guard against it, even better.
Or someone who has problems with spelling, but mitigates against it by asking someone else to proof important documents.
Behind the question the interviewer is looking for self-awareness and evidence of learning from experience as well as honesty and integrity.
Hope that helps.
