This company is seriously messed up. If they decide to interview you, they will have the hiring team reach out to you directly. There is no HR round (no discussion of expected compensation, benefits, etc.). There is also no information on what the company does and what it's like to work there. To me, this is an immediate red flag.
During my interview, the tech lead dived into asking questions right away and they were basic OOP/C#/.NET questions. Once I answered all of them, he gave me a take home assignment to interface with Twitter's public API. When I noticed that it had a lot of requirements, I decided not to spend time on that.
Considering the interview experience I had and the overall smug attitude of the interviewer and the lack of information on the company, I'd say Jack Henry has a lot more problems that a software engineer will have to deal with once they accept employment.
I decided to withdraw my application.
Save yourself time and look elsewhere.
