Multiple Degree, Network Engineer, veteran, Mensa member with 5 tats...
IOW, your opion is worth exactly the electrons it took to produce them and not one millivolt more....
Oh I get it. I am fully aware there are exceptions - perhaps you didn’t read “Yes it is a generalization...”
I don’t care because the generalization is accurate frequently enough that it provides a valuable filter for my hiring.
There is a social cost to having tats, especially certain types of tattoos. Many employers do not care, but many of us do. And since I determine who I hire, my opinion, like it or not, carries more weight than a few electrons.
