Almost all IITs are excellent engineering colleges providing the best education and amenities. Yet there might be some comparisons that can be drawn based on common aspects like choice, infrastructure, and geographical location. Eventually, it’s a matter of your preferences and not the institute's worth. For example, if you are someone who considers Academics the most important factor to determine the credibility of an institute, then IIT Kanpur is the best choice for you. It has the toughest grading system and the entire focus is on studies. So if you are excellent in academics, you will remain at the top here. Both institutes face a certain level of locational disadvantage but IIT Kanpur is still slightly better in this aspect.

These colleges don’t reveal the separate weightage break-up for work experience, test scores, and other such factors. For the final shortlist, institutes such as IIT KGP, IIM C, and ISI Kolkata take these factors into consideration along with your performance in the interview. These institutes assign a good volume of weightage to the entrance examination score. So, try to improve your test score as much as possible.

One of my friends had the absolute delight to appear for the PGDBA interview conducted by a multifaceted panel. He shared his interview experience which might help you a bit. Before the interview began, he was taken for a Verification Round wherein, every detail of academics scores or other profile-related information was cross-checked on the IIMs format. Once they received an IIM-verified document they were escorted to the interview venue. The interview room had 3 panels; one from each institute obviously. They asked for his brief introduction first. On hearing about his interest in Data Analytics, panelists probed him further with questions like What is Data Analytics Difference between analytics and analysis Contemporary Data analytics and ML They further asked him why he chose Analytics. He told them that the increasing demand for the same in Europe and China made him realize how much India lacks in this aspect and thus he wanted to invest his efforts in Data Analytics. Next, he was tested on his knowledge of Statistics and Mathematics with questions like  Difference between mean, mode, Media Skewness Relationship of mean, mode, and median in a positive Skew graph Hypothesis Testing What is Anova The next panelist took the reins and gave him a problem from SPC quality control. He asked him how do you know that his process in electric bulb making is as per customer Norma and is statistically controlled. My friend was able to answer most of the questions confidently and even solved this problem through charts.  Lastly, he was asked about his extracurricular activities and hobbies. The discussion ended with him asking about GST and the difference between GST and previous tax. Even though he gave a common answer, he managed to convert the interview.

ISI Kolkata is the best option for MSc in Maths, followed by IISc. IIT KGP is reputed in the technology domain, but for core science subjects, it’s not a good option. If you are interested to pursue pure Mathematics, choosing ISI is the best option among these. It specializes in the field. You will get better career opportunities and exposure in the field.
