Interview involves two stages - technical round followed by HR round.
Technical interview is detailed interview in which you will most likely be asked about projects you have worked on and the technologies used related to that project. You will also be asked some questioned on data structures and may also be told to write some logic (second largest number, reversing a string etc). Confidence is the key- be confident even though you posses little knowledge in any topic during interview and prefer not to fake in any interview, just be yourself- tell it on mouth if you know the answer - its ok.
In Hr round you will be asked about your weakness and strengths and be ready to justify what you stand for. You will be asked about your hobbies (most of the things asked will be from your resume). be fearless in HR round and give it from the heart. All the best!
