The choice of a Resume Format for mechanical engineer would depend on the qualifications and experience of a candidate. If you are an experienced engineer, then you should go for a Resume Format, which places more emphasis on experience and expertise, whereas for a fresher, a Resume Format emphasizing on academic background and training will be the better choice. A good format will have a title headline that is followed by summary highlighting qualifications of the candidate. A format containing a quick list of core competencies can be good to spare more space for experiences such as experience in ISO standards, analysis of root cause, problem-solving ability, etc. a traditional headline will work for the experience, but it should lay out the duties rendered in detail after the headline. Successful projects should be mentioned in the experience section or a separate section for accomplishments.
