Overall interview is Little much touch but if you prepare well it's easy to crack it. My interviewer asked questions related to what I have given in my resume, so please be true while preparing your resume. Then they asked me SQL, Java i don't know much i answered basics but they told me to learn it since it's useful. For some of my they asked core questions so if you are from other departments other than cse, It prepare your core basics also. That's all it's pretty good experience. Best of luck for you guys
