The idiocy of recruiting. In my experience a lot of companies actually want jacks of all trades when they hire someone. But the job descriptions are always tailored to specialist roles. Me personally I also stopped trying to market myself as a generalist instead focusing on specific topics with deeper knowledge and this has helped so much.
