This is a real pity, any idea why?
It is certainly the case that I have failed to get jobs in the past because I am overqualified. I’ve never been sure if that is because my prospective new boss has thought I am a threat to his future career or a belief that what I am applying for is only a stop gap and I would be looking to move on once a better opportunity presented itself.
The only thing I can suggest here is to tailor your C.V. (Curriculum Vitae) or Resume for the position you are applying for. You must remain honest in all cases but only mention what is relevant for the position you are seeking.
For example, my aunt (not really an aunt but a close friend of the family) used to run a small private hotel (or B&B) in the seaside town of Blackpool. When I was younger I used to help out as a waiter and later a bar tender. When I have been looking to supplement my main income with a little extra cash by working in hospitality this features prominently on my CV, my graduate and post graduate qualifications do not get a mention except to state that whilst at university I worked in a number of bars and restaurants
My main CV plays up to my qualifications and technical strengths and does not mention hospitality work at all. If an employer is looking for a senior electronics engineer then the fact that I know how to pull a pint is not relevant to the job in question so does not get mentioned.
Your resume, or CV, needs to be honest and truthful but should play to your strengths as they apply for the position you are seeking.
