First, you have to take a 1 hr written test (MCQ) based on Java, SQL and aptitude, about 60 questions. Following which, you undergo a face-to-face interview where you are asked questions mainly related to your resume. I think that the interview questions are largely reliant on who your interviewer is. For mine, he was really friendly and shared a lot on their work and day-to-day responsibilities. As long as your foundation is decent, it should not be too difficult.
