Think about how your customer service experience can be applied to project coordination. Did you lead the roll out of any new processes? Did you intake feedback or identify issues, work with others to figure out what to do next, and coordinate with others to take action? Did you set up processes that helped day to day work go better? Most jobs can be applied to protect coordination, so spend some time thinking about this, and then up date your resume and cover letter if you haven’t already submitted! Good luck :)
