Ques. How is metallurgical and materials engineering at IIT Ropar?

● Top Answer By Aaditya Hari Nair on 07 Sept 21

Ans. Metallurgical and Materials Engineering Department at IIT Ropar offers a B.Tech program, alongside a Ph.D. program. Since the establishment of the branch, it has involved a wide range of study areas, in India as well as other foreign countries. Mainly, it has shown a great scope of exposure relentlessly in these few years. Sir P.K Raina, considered one of the main heads of the institute, is a Ph.D. holder from IIT Kanpur and knows how to incentivize new talents. At present, he is known as the Students Associate Dean of IIT Ropar.  In terms of infrastructure, there is a separate building in the permanent campus, usually called the Satish Dhawan for SMMEE. There is a provision of only one lab located in the Transit campus - 1 of XRD. Other similar labs are located elsewhere, RMML (Ropar Machines of Materials Laboratory ) Material Testing Lab In case you are about to pursue your higher studies, then going for IIT Ropar is not at all a bad elective. Read more

Ques. Should I go for civil engineering or metallurgy and material science engineering in NIT Trichy?

● Top Answer By Aaditya Hari Nair on 31 Aug 21

Ans. I would suggest you go for metallurgy if you plan to do a job right after completing your degree. Metallurgy has more job opportunities to offer. With Metallurgy, you can easily learn coding and go for tech companies. NIT Trichy has a great coding culture, so picking up coding skills will not be difficult.  If you plan to prepare for civil services or any other government job, I would suggest you go for civil engineering. When compared to metallurgy, there are fewer job opportunities in the civil department. If you plan on doing an MBA after having done your engineering, you can opt for either of them because then it does not matter anyway.Read more

Ques. What is the current placement scenario for metallurgy and materials engineering at NIT Trichy?

● Top Answer By Aaditya Hari Nair on 30 Aug 21

Ans. One of my friends graduated from NIT Trichy and here are some facts about the institute I got to know from her. As you have not mentioned any specifications, let me just describe the placement scenario of Metallurgy at NIT Trichy. The placements generally vary from year to year.  Out of a batch of around 60 students, people looking for placements every year is around 40. The rest of the people either go for higher studies or have some other plans.  Most of the people get into material science-related fields at very good universities. Out of the 40 students, around 30 usually get placed.  Companies that usually open for metallurgy graduates include, Core Metal (steel/ aluminium), Automobile, Analytics, Software and others. There are a few companies that are regular visitors. The rest depends on the market and your training placement coordinator. Placements for metallurgy students are lesser than the other departments. Categories Metallurgy and Materials Engineering at NIT Trichy Course Fee 5.65 lakh Highest CTC 22 LPA Average CTC 10-12 LPA Recruiting Companies BPCL, L&T, Tata Steel, Reliance, etc. So, you need to act upon those selected shots you get. You'll have many chances throughout the year. You will also get a lot of guidance from immediate seniors.Read more

Ques. How is NIT Calicut for a B.Tech in material science?

● Top Answer By Aaditya Hari Nair on 26 Aug 21

Ans. B.Tech in material science in NIT CALICUT is a slightly underrated course as it is newly introduced. NIT Calicut also has an M.Tech course for material science.  The material science branch in NIT Calicut is a very promising branch despite being an underrated and newly introduced branch and has become an important part of NIT Calicut. This branch also has a dedicated department for nanotechnology. Recently they have made their college proud by preparing and distributing hand sanitizer in the entire campus and also in local sections of society to fight against the coronavirus pandemic.  The placements of this department are not as great as in the computer science department as it is a newly introduced branch.  This is a research-oriented branch with a strong alumni network. Material Science is definitely a promising field and offers a lot of opportunities in higher studies. If you love nanoscience then you should go for this course. Read more

Ques. Which is better, metallurgy at NIT Warangal or an MSc in Biology at BITS Goa?

● Top Answer By Aaditya Hari Nair on 24 Aug 21

Ans. One of my cousins recently encountered a similar situation where she had to choose between an M.Sc in Chemistry at BITS Hyderabad, and Biotechnology at NIT Warangal.  Having a conversation with the seniors, she found out that placements at NIT Warangal for Biotechnology, Metallurgy, Civil, and Chemical, are not as good as they should be. The recruiters are a handful, like Dr. Reddy’s, who recruit a few students out of many. Most of the students begin preparing for CAT or GRE during their 3rd and 4th year of the course. The ECE placements are quite reasonable. This means, the median package for circuit branches in BPHC can range anywhere from around 10 LPA to 11 LPA, while the average package can still be higher.  However, Metallurgy will not supposedly bring as many prospects as other branches can. It can pose a real problem in your case. You can choose to pursue an MBA or opt to study abroad for an MS.  But, M.Sc in Biology at BITS Goa can possibly be a good choice because you will still secure a position in EEE, ECE, or ENI. It can fetch you a position in the IT sector. The placements between BITS Pilani and BITS Goa are almost in the same range, with little to no difference at all. Only recently, there are candidates who went abroad to MIT or Caltech after their M.Sc, to pursue their thesis. It can make an easy dodge for you to secure seats in MS or Ph.D. programs. Thus, going for BITS Goa can be a superior choice to the NIT Warangal. Read more
