I did not have much serious interest either and considered my resume really strong. I quickly started wondering where the disconnect was.
Since I was laid off, one benefit I was given was access to a placement company. They helped with my resume formatting and I had a human coach who I met with a handful of times who initially helped calm me down but also gave me pointers on my online presence (LinkedIn profile). The companies website had videos that went over resume building, interviewing, negotiating etc, but I honestly didn't find them as useful.
If you want to message me I'd be glad to help. I can look at your resume (not an expert) but am in IT (solution architect) and can at least compare it's layout style to what I ended up with. I can try to remember/write up the things my coach had me change on my Li profile.
I don't know if I have much info/help to give but I can share what I did.
Very cool, downloaded and will start using It!
