Another frustrating tactic they have started to use is bait positions with attractive "specifications". They use these to draw you into communicating with them and start offering subpar positions than those initially mentioned in the first communication. The classic bait and switch.

I'm fed up getting messages on LinkedIn along the lines of:

Hi LeBowen You are exactly what TheWorldsBestCompany are looking for, is it OK for us to have a phone call to discuss?

Of course when you try to obtain any information about the position, you're met with vague details about it, but they have this other position you might be interested in.
