This is the reason why employees requests their managers to issue an experience letter at the time of leaving the job, so that they can use it while applying for other jobs. Employers also check that the experience letter is written only on the letterhead of the company, as many job seekers now submit fake experience letter to support their claim of previous job experience, even when they have none.
Employers now usually ask candidates to submit their work experience letter certifying their previous work experience to make sure that the candidates hold a valid experience, and five years or ten years experience that they mention in their CV is not a hoax.
