How would you handle varied work locations?
The question is, how would you handle varied work locations, such as working in one office one day, another the following day and the main office the day after that?
I think I'd list the main office on the resume and then explain what you said above either in the cover letter or when you go on the job interview. The resume is really used to list the location of the employer more than a specific location where you worked. For instance, if you had a job that required you to travel to another country every couple of weeks, you wouldn't list those locations on the resume, would you?
