If not, I'd think about it if I was a hiring manager.
--I haven't used Linkedin as a recruiter since the new UI update, so this may be different now.
Company A decided to something really smart: they organized an information session just for Company B engineers. I sent over the invite and 10+ engineers from Company B joined our after work event. We had free food and drink (important) and an overview of our company; our CEO asked our team to stay over afterwards to socialize and answer questions. They also had an open invite to any engineer to come onsite to interview the next week. We basically structured it like an on campus recruiting process. The event cost us maybe $300 and we ended up getting 4 of their engineers, all of whom who stayed for over 3 years.
Company A actually had huge issues, but that was the smartest thing I saw them do while there.
