The thing to keep in mind here is that your application is technically a legal document in which you are verifying that everything you say is true and accurate, while a resume is not. While it might seem reasonable, even logical, to only list the positions pertinent to the job you are applying for on resume, you must list your most recent jobs in chronological order on an application. If there are major discrepancies between your application and your resume, then an employer is likely to question your honesty (and may not ask you about it to give you a chance to explain, especially if they have a high volume of applications). Therefore, it really is important that you list at least the most recent previous employment. If none of those jobs are relevant to the jobs you are applying for now, then you could consider lumping them together with the span of the dates and simply stating something to the effect of “various entry level jobs while looking for full-time work in my career field” but you should be prepared to speak to what some of those jobs were if asked and/or list some of them out on the application.
Additionally, you should consider what skills you learned from some of those jobs (i.e. project management, administrative work, etc) and see if it’s appropriate to list some of these in a skills section of your resume or under the various jobs heading. Many employers understand the possibility of applicants having more sporadic work during and just after college, especially with the job market being what it has been the past few years.
Good luck and just be prepared to speak to the work you did, as well as the skills and experience gained from it, which will benefit both you and the company you are applying to. Thanks!
