Does it affect at IIM Ahmedabad if you are not from a prestigious institution?

It makes little difference in terms of interview call conversion at IIM Ahmedabad. If the interviewers believe that the candidates (from whatever institute they completed their graduation) are qualified, they will hire them. In fact, if they have to choose between two candidates who are equally good, they will most likely choose the candidate who graduated from a less well-known academic institution. They receive many institutes from well-known colleges, but having a student from a lesser-known college can bring a unique perspective to the class.

Coming to the point of impact of college graduation at IIM Ahmedabad. Impact on various levels:

• Academics: Everyone must earn their grade by performing well in quizzes, exams, and, most importantly, group projects.

• Club selection: It is dependent on the person conducting your interview for the selection. However, it cannot be assumed that a person who did not attend a top-graduation college will face disadvantages.

• Placements: It may have an impact on the placement process. Recruiters may prefer a candidate from his or her college over others. Because the likelihood of a recruiter being from a "prestigious college" is higher, the individual may benefit.

The biggest advantage is that there is a culture in these colleges of getting into top B-schools, so students believe they can do it. They can also get information from seniors regarding the same.

Well, the answer is yes. Because if there are two aspirants with the same CAT scores and academic grades, then the reputation of the college matters a lot. The candidate from the prestigious institute has better chances to be selected.

You will understand better if you put yourself in the interviewer's spot. Think of yourself as a recruiter and you have to select one between two candidates, one is from IIMs and the other is from another college. Whom will you select?

If a student from a reputed college, the college’s reputation stamps on that student's hard work and capabilities. This is why IITians are so much appreciated. 

If you are from a reputed college, the interviewer will naturally think you have the potential to be selected for admission. However, if you are from a non-reputed college you need to prove your intelligence and convince the interviewer why they should select you over others.

This is not discrimination. Rather, it is an easy way to be selected in a good profile with low risk. Being said that, the interviewers are open-minded and will not make up their minds before interviewing.
