Discussion started with the projects mentioned in my resume.Detailed background questions based on projects were asked.As I had mentioned about the Distance Matrix API ,I had questions on how are these are actually implemented..Questions on Datastructures were asked.

Started with well-known question "Tell me about yourself".Then asked about the family background and hobbies.Asked about the strengths and weaknesses.
Then asked why computer science and not other branch.Then he was testing whether am I interested to do any higher education after B.Tech.Asked about the long-time goals.

In group-discussion try to participate as much as possible and speak valid points with examples supporting your opinion.
In technical round should have deep understanding about your projects and good grip on Data structures.Be prepared with an answer if asked about the variations in your SGP.
In HR round speak confident and go prepared with how would you answer above questions as these are generally asked in every interview.
Go through their company's website before attending interviews.
