<human>: Can you summarize the given text in a few sentences?

Like the title states,  I have a job interview on Friday at a company that I have been wanting to work at since I got into this field of work.  I was preparing for the interview by doing some research on the company's website and I came across the staff section and there was her name.  Let's call her Betty. Back story on Betty,  I worked with her for about a year at my old job,  I was her manager. I hired her. She is young, loves drama and gossiping, a pathological liar, talks horrible about previous employers and jumps  from job to job. She stirred up a lot of drama the year I worked with her and was not a good employee at all.  

I was fired after 4 years at the company. My boss hired somebody to do my job for less, even though I was a dedicated hard worker. After I filed for unemployment my boss tried to deny it saying I had threatened another employee and that's why I was fired.  Not true at all and was never stated when I was fired. I had to do the whole hearing with the state and submit documents and evidence to get my unemployment and she submitted hers, Which was a written statement made by Betty stating I threatened to punch her in the face, and she didn't feel safe working with me. None of this ever happened.  This girl just loves drama and lying. I never contacted Betty to confront her for lying, I just blocked it out and moved on with life. Long story short with that, I got my unemployment because i proved the story untrue. 

Fast forward year and a half, I am looking to leave the company I'm with now and landed an interview at my dream company but betty works there. It looks like she is a new hire. I'm devastated. I'm at a loss at what to do. I'm secure in my job now so I'm not desperate for a job by any means. But I don't know what I should do at this point. I've waited years for the right time to apply here and now this crazy girl is there.
<bot>: got dream job interview but crazy drama fueled ex-employee works there. Don't know where to go from here.
