Intercontinental Exchange interview questions

Had 3 interviews, all online. After the first interview, they had me meet with 2 employees. One did a great job with providing a good layout of the company and what day-to-day operations looked like. The other, unfortunately, was very dry and lacked engagement. After all interviews, I was ghosted, even after following up with the first interviewer, who passed me on to the next steps. I know ghosting is normal now, but you would think a company worth roughly $137 billion would have automated rejections or feedback set up.
