First of all, IIT Kanpur does not offer Biotechnology, rather it offers Biological Sciences and Bioengineering. This is a good choice for those who don’t have any specific interests and are ready to study biology. In IIT Kanpur your CPI values much more than your branch. So don’t waste too much time deciding on one and just go for any of it.
Placements: IIT Kanpur has both core and noncore jobs in abundance. Core jobs are a bit lesser than non-core jobs with only a handful of core companies. However, the majority of recruiters offer non-core jobs for which the only requirement is a good CPI. Here, your branch does not matter and the role offered is nothing related to your branch. To a certain extent, non-core packages offered are better than core packages so most students prefer this.
Curriculum: The ocean of electives available to choose from at IIT Kanpur, makes it possible for students to explore much more than their branch. You are also eligible to do a major or minor in any other branch provided you fulfill its minimum CPI criteria. IIT Kanpur also has a branch change faculty at the end of the first year. All this flexibility makes IIT Kanpur’s curriculum a much coveted one.
Lastly, I would like to comment that your choice of Institute is also crucial. The opportunities and exposure offered matter a lot and IIT Kanpur offers it all!
