Or it's like companies who cast a wide net saying you can make up to...... But really they always pay far below that. They don't care if you quit after 6 months or a year, because they are always casting a wide net and were playing the numbers that they won't ever have to pay you or anyone that amount for the position.
That tatic is widespread.
Not all places are like that, but they are not always hiring and are more selective and harder to get into.
I may not be the sharpest tool in the shed, but I can simplify most things and I've gotten really good at spotting bs. Probably because I've stepped in it, fallen face first into it, rolled around in it, several times.
