I was going to write a similar comment when I saw yours. We've recently hired someone who was great on paper, was adept at talking about software/programming and was able to present some code he allegedly wrote and explain it. He seemed like a great fit based on the discussions but we hadn't actually given him a whiteboard interview.
Once he joined the company he proceeded to actually be completely unable to write a single working piece of code. Everything he wrote needed to be reviewed and had major glaring issues. When confronted about it, he would say that he couldn't figure it out so decided to just commit his unfinished code.
That guy was senior, had worked for 20 years and is really good at talking but when it comes to actually developing software, he is completely utterly incompetent.
I am constantly surprised at how many Brillant Paula Bean [1] developers are out there successfully interviewing, getting hired and BS-ing their way through jobs. I've always wondered if this is as prevalent in other industries outside of software.
