I'm a university student applying for part-time and full-time contract jobs. I just moved to the US (from Canada, where I did two work terms) so I'm going to need more than one part-time job so that I can pay rent, university fees, etc. I'll be applying to quite a bit of jobs over the next month or two. Right when I began my job search, I found a part-time job which requested me to provide references during the application process itself. When I lived in Canada applying for work terms, I normally was asked to provide references during the interview step (meaning the reference should expect a call within the next few weeks for sure), and right after the interview step, if I got the job, then my manager would not have to expect any phone calls about me anymore (because I was only looking for one job back then).
This situation is a bit different. Not only will I be continuously applying for jobs because I'm looking to work more than one job at a time (so my managers will have to be a reference for quite some time), but this job posting requires me to provide a reference during the application process itself (so it's not even a guarantee that they will call my previous manager because I didn't even make it to the interview step yet).
I think it is an inconvenience to my previous managers to have to expect phone calls about me for the next month or two. With that said, what should I do in my situation (applying for jobs for the next month or two and planning on taking multiple jobs at once - which means multiple companies might call the reference. On top of that, some companies request a reference during the application process itself so it is no guarantee that a phone call will come at all)?
