ASEs are hired from tier2-3 colleges. Campus placements are usually done in 7th sem. Interview aims at finding boys and girls with right attitude to work and who are ready to learn. The process involves an online test that aims to check their English language and problem solving skills. The next is a f2f interview which basically checks that the interviewee has done some preparation, wants to have a job, and has studied something(or good in at least one subject). So, interview usually starts with 'tell us one of your favorite subjects in Engg' or if you are lucky: 'to explain your summer training/projects undertaken'. The interviewer might grill a little on various aspects but in fact, it is still at overview level - and is actually verifying whether you are able to explain yourself, you are able to understand him and give a sane answer.
