I know Mechanical Engineering is vast field and it has now lots of depth and different sub fields so its way too difficult for any mechanical engineer to have all the skills and knowledge and hands on experience on all the tool.

so i want to know for specific kind of job what knowledge, skills and experience a person to have so they could get that specific job.
