After a successful interview I received a job offer. I already had another job offer so I was wanting to negotiate after finding out more details about the position. I sent a polite email asking if they would accept a counter offer (which wasn't even much more). No reply, nothing. I assume this means they withdrew the offer but didn't even bother to inform me? Extremely unprofessional and rude. Anyway, they certainly helped me decide which offer to accept, and it wasn't theirs. Looks like I dodged a bullet.
