Stanchion Payments interview questions

I was supposed to have a meet and greet chat but turned into a mini interview, but it was basic springboot and other simple programming questions. The interview itself lacked substance it was like he didn't know what to talk about and only saw my CV when we were talking, very unprofessional to be honest. The role what for immediate but I was asked graduate level questions!

General IT Interview. Multi step process, which includes things like Initial interview, Tech tests as well as a general meeting of the team. Finally there is a final interview, offer will then be made.
