What is the placement record of chemical engineering department of IIT Guwahati?

The placement scenario of the Chemical Engineering department of IIT Guwahati is just average with only a handful of companies visiting the campus for placements. The packages offered too are not at par with other IITs. 

My sister was a student at IIT Guwahati and she told me that many of her batchmates remained unplaced. Specifically talking about Mtech, core jobs are scarce and only your luck can help you.

I will recommend you entirely focus on preparing for PSU or GRE and target a Ph.D. from a foreign university. The professors at IIT Guwahati have good connections abroad and their reference and guidance will help you to choose the best universities, and publish good research journals. Ph.D. students have to do the job hunting themselves and not rely on placements. 

Those who opt for non-core placements can avail the best opportunities with great packages even better than the core. All you need is a decent proficiency in coding and knowledge of a few programming languages.
