We can let go of DTU SE as we already have DTU IT here. NIT-D is nowhere in competition with the other institutions in the current scenario. Now, we are left with DTU IT, MNNIT IT, NIT Surathkal IT, and NSIT ECE.

Here’s a brief insight into the courses mentioned in the question. 

To be honest, ECE is a branch that is dying when compared to IT. Some time ago, ECE had better cut-offs than IT, but it is evident that a lot has been transformed since then and is seen in the trends. Therefore, we can clearly eliminate NSIT ECE.

MNNIT Allahabad is a really good institution for the course but when it is compared to the other two unbeatable colleges - DTU and NIT Surathkal, it does not even stand a chance.

It is quite a difficult choice between the two - NITK and DTU. When compared with DTU, the Academics are better at NITK. Yet, on the other hand, DTU has a better set of peers, luring placement opportunities, and a more modernized campus. NITK has the brand tag of NIT while DTU has the brand tag of DCE.

Now, the choice is yours. One of my friends had the same conflict a few years back and choose to go for DTU IT.

Yes, this is possible. Amity University has a centralized placement committee, the Amity Technical Placement Center (ATPC) along placement committees at every campus. 

The Noida campus of the university hosts many top companies during its placement process and students across campuses participate in the process provided they have the invitation letters. There is no fixed seat.

As far as a Biotechnology course is concerned, then it has a very limited appeal among recruiters. However, you can still apply to various IT companies that visit the campus. 

Being a student at Amity University Gwalior, you can definitely get a seat at Amity University Noida for placements, especially in the initial phase of placements. But it is always better to check with the relevant authorities to get a better picture and clarity about the various processes about the same.

VSSUT Burla is a much better option than IGIT Sarang. VSSUT, Burla - Being the Oldest engineering institute in the state, has some of the best faculty, a huge library, and a wide-spread Alumni net.

Discussed below are a few important points about VSSUT Burla.

• For any branch, VSSUT will be a better option, since it has better placement records, campus infrastructure, clubs, and the cutoff rank is also higher. 
• Most importantly it's autonomous so it has its own examinations and curriculum.
• If you have any problem regarding something you can directly get in contact with the Vice-Chancellor at VSSUT Burla. 

The table below gives a brief overview of the institutes.

One of my cousins was in the same situation, whether to choose VSSUT or IGIT, and he chose VSSUT. If you look up the statistics you will clearly see VSSUT is much better than IGIT.

Talking about B.Tech CSE, Sharda University can be considered a better choice than Northcap. It is a very well reputed institution in terms of opportunities and respective training sessions in technical sectors for the Global environment. 

Academics: 

• Northcap University, which however is not as well ranked as Sharda University, is also incapable of providing the required amount of exposure as needed for the industrial sectors. 
• On the contrary, Sharda University being a greater institution in itself has various tie-ups with other higher organizations and foreign universities.

Faculty: 

• Sharda University is bestowed with extremely friendly and highly professional professors which rather is the greater plus point for any respective stream. 
• Northcap, as even mentioned by some of its students, comes up with a very poor record of having a group of inexperienced and unsupportive professors. The employability you will attain after pursuing B.Tech from Northcap is uncertain.

Sharda University has recorded well for the past few years to provide a good deployment rate in the B.Tech branch. On the upper hand, various organizations like IBM, TCS, Tech Mahindra, and more have arrived occasionally for campus recruitment every particular year, and students of the university are offered 2 LPA to 5 LPA without hesitation.

My friend is an alumnus of IET Lucknow and according to him, with a rank of 5915, it will be hard to get Chemical Engineering. In his year, only a few general category students received Chemical in the fifth round with a general rank greater than 6k.

However, because the scenario changes every year, there is no certainty that you will get it. Also, given HBTI's split from UPSEE, getting into IET with this rank appears to be extremely difficult. It's all a matter of luck. 

According to the cutoff trends in recent years, the required cutoff for the Chemical branch is 2856 for General Category.
