I've got so say, this is a very cynical bunch. I probably should have expected some of that since that's a valuable trait in structural engineering, but goodness, the level of suspicion and cynicism is really surprising to me.
Also to agree with some posters, I have no interest in LinkedIn beyond recruiting. Every now and again, someone will post something about an interesting building that's being erected that I'll find interesting/educational. Mostly though, if I scroll LinkedIn, I have to keep telling LinkedIn that I don't want to see the political/religious/personal content that people are posting. In a perfect world, LinkedIn would be a place to network, recruit and show what's possible. Mostly though, the same type of people who made me cancel Facebook years ago feel the need to post their views on guns, religion, politics or whatever non-job related topics.
That being said, it's valuable for recruiting and I've sometimes had great success using it to find people. However, it's a limited resource. Based on what I know, I'd estimate that only around 5% of engineers in my industry have a profile that makes them findable. To be candid, I'm looking to steal the best employees from other companies and a lot of those employees could benefit greatly from allowing me to steal them. This sub seems very dubious that I somehow work for a reputable company that would be offering an upgraded situation. Think of it this way: are you capable of figuring out if a new opportunity is a good one? You are? So are the people I'm interested in.
In conclusion, I'd like some of the posters here to comment on the idea that's been thrown out that if your company is any good, great employees will be sending in unsolicited resumes, making recruiting unnecessary. Is that an actual reality? I've been in some part of a hiring position for around 10 years for different companies. I've had a handful of randoms send in unsolicited resumes but never anyone of any quality. Is this really a thing or is this idea just being thrown out to troll. Whether or not you posted one of the comments saying that this is a thing, I'd love anyone's opinion on whether or not they think quality professionals are in the habit of sending out unsolicited resumes to "good" companies. If it is, I've got some work to do.
