Trending @Infosys; Regarding Job Preparation

Hi friends,

I have already completed 4 years with infosys,in my first project I was like a fresher so I didn't got much work, almost 1.5 Years I was working in that project. And in my second project I got chance to work on more tech like Angular, React,Xamarin, .NET and also GIS. Second project is like maybe 6 months in one tech, immediately next day they will tell to work on another tech..so I don't have any full knowledge in anyone of them. Because of this am in confusion which domain I need to choose, how I will prepare for interview, if they give any task in this domain I can do but for learning wise if anyone ask anything related to these am not that confident.. So now already 4 years completed I want to switch company but am not able to choose a domain, am not sure how to prepare, am not confident enough on these domain.. If anyone faced like this situation please guide me..it will be very helpful...

Thanks.
