Advice for Addressing Job-Hopping on Resume?

Dear Experts, There was so much valuable information from your Bucket List webinar on Tuesday. It was clearly presented! I must say, I was staggered by the quote about 15 minutes - the average job seeker devotes just 15 minutes a day to their job search. I literally regard my search as a full time job for the business of me! I recently had my resume significantly revised by a CAREEREALISM expert and while everyone who sees it remarks it looks very impressive, the problem of the illusion of job-hopping/not great longevity at all companies seems to be something of a roadblock. The job hopping is not a different company every 3 months or something; some were finite projects which I very successfully completed and then moved on. I know more progressive companies are not obsessed about the job hopping thing, but there are a number of professional services firms I would like to approach and it would be very helpful to get your insight on how to specifically address the job-hopping issue. I know companies are looking for incredible loyalty from their employees, and they think a history of longevity with former employers is their best guarantee for a prospective employee to stay with them for many years. That employers no longer exhibit incredible loyalty to their employees is worthy of note, but of course it would be churlish to point that out in an interview. Do you agree it would be wise to include a very focused, artfully phrased paragraph in my cover letters which addresses this issue? Many thanks for your responses! All the best from a big fan of CAREEREALISM! Here is how our CAREEREALISM-Approved Experts answered this question on Twitter:Q#442 You need to address why you have had so many jobs. If there is a legitimate reason, let them know. (@gradversity) Q#442 Go on offensive! Open cover letter/convo with: "Here's 4 ways trying several jobs has helped my career!" (@jtodonnell) Q#442 Specify what was project work in resume, identify your impact. In cover letter, tell your career story arc. (@juliaerickson) Q#442 Reframe as + in letter: "...gained valuable exp w/ short-term projects, but now looking for more permanent..." (@EmilyBennington) Q#442 If they were project-based, then explicitly show that. It looks more professional on your part! (@beneubanks) Q#442 Job hopping: I'd suggest explaining in resume if it is problematic. Network your way to job to avoid concerns. (@keppie_careers) Q#442 No guarantee cover letter will be read. Return to and work w/orig writer to revisit strategy if this one isn't working. (@DawnBugni) Our Twitter Advice Project (T.A.P.) is no longer an active campaign.
