Interview Preparation Tips

Interview preparation tips for other job seekers - Be honest. It’ll be appreciated to be honest if you don’t have much idea about it rather than being over confident. Also whatever you know about learn in detail. For example I was given to write a code showing inheritance, I was asked questions on multiple scenario it is important to understand the in depth of concept of all keywords like static and annotations (@override) as this is basic but we need to know about how it works and what exactly happens when we don’t have it.
