Focus on Academics or internship/volunteer work more than work history depending on your forte
If the job you wish to apply for is a relatively new field for you where you don’t possess the required work experience, but you have pursued a course on a related genre, or have earned stipend at an internship experience working on a related field, mentioning that in the resume at the very beginning after a professional summary or career synopsis would help. You might not have been paid for learning skills that are essential for the type off job you are seeking currently, but skills you have learnt. People who seek to change career paths and have many years of experience in a certain field however, really want to work in a field for which they have immense volunteering experience, should rather list down what they have learnt in the volunteer session at the very start.
