If you've ever run a company, you know how bad people's CVs can be and what you need to do to stand out. I recommend it to everyone. I would get 15-20 CVs for a small company, and I didn't even closely look at 10-15 of them because it was clear people were just writing random shit or applying without even looking at what we wanted.

I suspect it is a similar ratio for any software company.

My best hire ever was a math teacher in a previous career that wrote his own tools. Worst hire ever was a guy with a PHD that thought he was still in university.
