Honestly...
The last one looks like crap :p I was never an employee, but I would probably think it was taken from some coloring book.
I like the second one (except those little icons )

If I can give any advise - keep it clean and professional. Simple, to the point, important parts highlighted and easy to find.
Not sure what a future boss will like. Maybe some like to read all the sweet stuff (that most id exaggerated anyway most of the time)
