The only reason his resume "just suck" is because he probably doesnt have much experience. His interview skills probably do suck though as he mentioned he is having trouble landing interviews.

OP honestly it is probably just because there is a bit of a downturn in your field of work. My field is experiencing the exact same thing. The large majority of the small group that got hired from my graduating class already had several years (if not more) experience and can easily transition from school to work. If there isn't much work, companies wont hire fresh graduates/dont want to take a chance on graduates due to needing to invest time and money on training.
