KnowBe4 Order Processor interview questions

At first the interview process seemed to have gone well. After the initial interview, I recieved a call from the recruiter saying that they were ready to move forward with me but they were just waiting for the sales position to be filled to match my position. That was fine with me but about 1 week later I recieved another call to come in for a second interview to meet with the hiring manager. After the second interview, the recruiter told me that I would recieve a call within the next week with the official job offer. Well that wasn't the case, I recieved an email to let me know that they were moving forward with a different candidate. This was very upsetting because my time was wasted and it seemed like I was being dragged around for no reason and got my hopes up.
