Verifi Software Engineer II interview questions

HR emailed me, I had applied online. The HR setup first round phone interview with the CTO. I did very well in the interview and the CTO was very engaging and he explained me the team structure and technology stack in detail - Second round was on-site interview with the technical team (2 developers interviewing at the same time) The interview lasted one hour, it started with technical questions(Spring MVC, Database, Objecte Oriented Java) then I was asked to write code which was not very challenging. I got the offer but couldnot accept due to there Green Card policy.
