First of all, let's decode the job description. It is crucial to know your exact role and responsibilities, so you can adapt your resume to directly address the requirements of the job. For instance, if the job description requires the candidate to "interact and engage with customers", you should add that you have "excellent interpersonal skills" into your resume. Employers would be more likely to take notice of your application because you would be viewed as a more suitable candidate.
Aside from helping your resume to stand out, having greater knowledge of the job requirements would allow you to ask more meaningful questions during the interview - such as certain aspects you may be curious about or information gaps in the job description. This would leave the employer with the impression that you're sincere in understanding the role and view you as a diligent, viable candidate. However, note that every job's scope is different, and it would be ideal to tailor your resume to different job descriptions to maximise your chance of getting jobs in retail with no experience!
