Signify Health Graduate Software Engineer interview questions

Was invited to an on-site interview. Sat down with 2 non-technical recruiters for roughly 30 minutes discussing personality, CV etc. Then had a technical interview with a developer to solve an OOP problem on a whiteboard with some general OOP questions (defining polymorphism etc). Got an email shortly after saying I was accepted and would receive a follow up with specifics. The follow up never arrived and 3-4 months later, they emailed to say they were not hiring for the position anymore.
