Mosaic Transit Group Project Coordinator - Properties interview questions

I was interviewed through Teams. With the manager and HR. He asked a lot of situational questions. They pressured me to talk about my salary and what I thought was their salary. I waited for them for over 3 weeks to make a decision. They left me hanging until I had to email them and they said no. Since then, they have posted this job 3 times. Sounds like they are not even sure what they want. Waste of time!
