I purchased a deal to help my daughter refine her resume looking for jobs in the legal profession.
While she said that Resumeup helped organize her resume, she also had issues with generating cover letters. When she included specific wording from different sites for different types of jobs (law clerk vs. personal injury vs. assistant DA), Resumeup gave her the same verbatim cover letter. When she tried substituting job-specific words and phrases from the web sites to the cover letter, Resumeup downgraded the quality of the cover letter.
I'll hold on to one of my licenses just in case Resumeup improves, but at least for submitting legal resumes, it isn't quite there yet.
