Trane Technologies Software Engineer interview questions

It was an informal interview over phone with the project head. They wanted to develop an application in SpringMVC. Mostly the head asked me questions related to SpringMVC and how I will be able to develop the application they need. He was very friendly and we had a good conversation. I went directly through referral and in the next round with HR they asked me if I will need sponsorship in future. This is where they could not make an offer to me. If you don't need sponsorship then its a very good project to work on as you will get complete freedom to design the application.
