Fiserv Software Developer interview questions

Initial interview was a flop, as the scheduler didn't take into account time zones. They gave another interview an hour later, which lasted around 25 mins. Basic questions about the platform I'd be coding on, said the important interview was the coding test. Redirecting me to a github page that had instructions for building a basic app and a request to submit the result within 4 days. I then had a second, but in person interview, with the tech lead and hr. An offer was given the next day.
