It’s entirely possible you’re not getting offers because they know you don’t need them.
I don’t mean to say they’re wanting to give the offers to less fortunate applicants - it’s just that you’ll be impossible to abuse relative to someone who they know needs the money.
“We need you to work until this is done.” “No.” “Chris, it’s very important and will be reflected on your performance review.” “Ok. Still no.”
At the start of my career (ages ago now) I had an employer find out that my university progression was tied entirely to their performance review of my placement, and immediately start to insist on my working all the hours under the sun with the strong implication that if I didn’t play ball the note would be “unfavourable”.
When you’re young it’s not always clear how little crap you should take from people in more senior positions.
