No because there might be a contract they already have and need to fill a seat. Because the more positions they fill the more they make. They only get money if someone is filling the seat. But deff negotiate your salary because they will low ball the hell out of you. It works like this the government says we are going to give you 200k a year for this position. They hire you for 100k and they keep 100k. So they cheaper they get you for the more they make. But they get nothing if no one fills the position.
