Do any Celgene sales professionals understand that LinkedIn is a 'networking' app? When someone is trying to connect, you should accept their invitation. Especially when there is an open position in your region. Jeez. Effing idiots.
"Invitations" are not obligatory!! Send an in-mail or message with the "invite" and let the recipient decide whether or not it is acceptable to allow them access to your additional data or contacts. Many "invites" are like facebook "likes".
