Dear Student ,

Generally ,most of the  IT companies prefers the students those who are from IT background (i.e. have studied in CSE or IT background).

But , yes .. you're still eligible for online as well as offline campus interviews where the eligibility restriction is reduced .

The main topics you need to learn for preparing these type of interview is to learn Data Structures , at least one programming language proficiently, body language and attitude as well as dressing attire , ability to solve instant puzzles and relevant criteria in additional basis .

On the other hand , MCA students need to be well prepared as they are from pure IT background , so interviewer may expect an advance level of knowledge in IT field from you based on the syllabus or beyond the syllabus.

Hope you understand !
