Had a similar experience. Toxic company that was awarded a contract hired in a bunch of people, gave us starting dates then a week before we were supposed to start they delayed our start data by 4 months. It only got worse and worse from there. I eventually quit when I was doing 4 other jobs, like with different pay scales and supervisors and everything, by myself. Killed any chances I had with IT since every other company around here doesn’t want to risk yet another burnout from that place. I had the same place interview me twice 6 months apart and both times as soon as they saw that company on my resume they frowned and kind of cut it short.
