When you are applying in any educational institute for a job, you need a resume stating your skills, degrees, accomplishments and experiences. The CV should be unique and convince the employer about the suitability of the candidate for the position.
This format is also beneficial when you are hopping your job field. As it is more focused on the skills of the applicant, you can mention your prospective job relevant skills in resume to prove your suitability for the position. If you do not possess the skills required for the applied position, you can frame your current skills to match the requirements of the employer. Functional template will definitely hide your job hopping or employment gaps and gives you the opportunity to grab your dream job.
