USAA Decision Science Analyst interview questions

This interview process is very long. I am talking about a 3-month long interview since application. Very nice and pleasant HR lady gives screens to you and gives you initial information. After that, it took around 10 days to schedule an interview with the hiring manager. He was super nice as well. Three weeks later got the third round with the panel. They told me they will let me know in less than 2 weeks. Well, 20 days later nothing. They just ghosted me. I emailed the HR lady that was scheduling everything, Nothing. No replay. It feels now like it was a huge waste of time. At least tell people that You went with another candidate don't ghost them.

Initial had a phone interview with the company. They then flew me to their main office in San Antonio for interviews. Mostly behavioral question. Interviewed with a few different team members from the head of the team to new employees.
