I graduated college in May and had a job offer rescinded one day before my start date and am now out of a job, including the job I left to work at my new place of employment. i made the mistake of cancelling other interviews not knowing that the contract I signed was going to be rescinded within 3 weeks of signing. I made it through five rounds of interviews over two weeks, and was never given any flags of concern or hesitation. The same day my would-be boss called to let me down, someone from HR also sent an email further anticipating my arrival and onboarding. Talk about mixed signals. To make matters worse, they decided to let me know at 6pm Friday night going into a long weekend not to show up the following week. The contract I signed was at-will so what they did was legal, but it certainly feels unethical. They gave me vague reasons for my dismissal, including the economy and “board meetings.”
I've applied to over 300 jobs on LI, Indeed, etc. I've had interviews from multiple companies but I turned another offer down to accept this one. Since this event, I've applied to a bunch more and keep getting rejection emails. I haven't had any interviews or phone calls since. I feel jaded now, and scarred from this experience. I don't even know how to regain the enthusiasm I had before this situation. I consider myself a hard worker, and I set goals for myself, but this past week has been such a struggle for me to even get out of bed. I feel like I just wasted 6 weeks of my life. I keep considering going back to my first job out of high school, but the idea of that feels so depressing and demoralizing.
At a loss on what to do, I'm feeling so depressed and hopeless now. I've never been unemployed in my life. I graduated at the top of my class in both high school and college, I am excellent communicator, I have loads of volunteer experience and I worked straight through the pandemic. This is really taking a toll on my mental health. Any advice or words of wisdom appreciated.
