Seems that they tend to hire penultimate year students as their interns, they number of vacancies is not high so i would say that's the toughest part. Seeing from your description about your background, it seems to me it is possible to pass the screening and it should be more depending on the interview. It is said the interview contains questions that not too very technical, but definitely you should study more on their official website on the exact job duties if you are invited for an interview.
