I did the CompTIA A+ about 18 years ago and it served no purpose whatsoever in getting me a computer job. It did set me back 1200 quid, though.
My mate did it about 5 years ago and directly after got a gig fixing shop self scanners. But he wanted to be doing other stuff and found it didn't really get him where he wanted to be, either.
Be careful with it. It's a feather in your cap for sure but it's not that much of a boon.
