The Whiteboard is nothing more than a hazing ritual testing marathon runners on their 100-yard dash. As CTO I opted to go for two-pronged:
1) give them a take-home project in an area relating to the position they want to weed out the unqualified.
2) bring them on site and speak with them in persona along with other members of the team they will be joining.
3) Its fairly easy to tell whos a whos an impostor if you are knowledgeable yourself, but a group of engineers can identify a faker fairly quickly.
4) Always consult your team about the new hire and don't make it unilaterally or their failures will reflect on you. Even their success won't make up for it if they turn out to be a nutjob and you vouched for them.
