In terms of college, IEM and HIT both provide similar career opportunities in the IT sector. Major recruiters like TCS, Infosys, CTS, Capgemini from the IT sector visit both the institutes. 

If you had to pick between the two engineering fields, you should always go with CS. If you select CS, you will be able to apply for a variety of government/public sector positions (ISRO, BARC, IOCL) after completing your B.tech. Only CS guys are qualified to apply for the majority of these government jobs. 

As you will get similar opportunities you can choose either. Also, outside of WB, no one cares if you're from IEM or HIT. Unless you're from JU, everything is the same.

Among the above three institutes, IIIT Gwalior is the best choice, considering the fact that it is the oldest IIIT and offers excellent placement and academic facilities. The preference order of choice among the institutes is given below.

IIIT Gwalior > IIIT Jabalpur > IIIT Lucknow

The table below gives a brief level of comparison among the three institutes.

Key Highlights:

• The cut-off for admission to IIIT Gwalior is a validation of the fact that it is the best choice. It has its infrastructure spread across a 100-acre campus, being the oldest IIIT and maintaining its standard of placement and academics.
• Jabalpur has a 260-acre campus. In terms of placement and infrastructure, it comes just after IIIT Gwalior. But in terms of research, IIIT Jabalpur is ahead of the other two.
• IIIT Lucknow has a 50-acre campus and is mostly under construction, and is just 2 batches old. It is growing with time and needs to gain fame eventually. IIIT Lucknow has good placement, even in the first pass-out batch. It would be an excellent choice in the future if the records in placement are retained.

Therefore, the above order is the choice of preference a candidate will find relevant. No candidate should be misguided just by recent placement records and statistics.

If you are planning between these two, NITC CSE is a really good option. They offer cushy packages and decent companies visit the institute.

According to the recent placement report, the highest package offered is INR 49.75 lakhs per annum with an average of INR 11.58 lakhs per annum. A lot of companies like Aakash AESL, Bosch, Nokia, and HDFC visit the college.

When it comes to MNNIT the course curriculum of both IT and CSE is the same and there is no such difference overall. The placements are good too. The highest CTC offered is INR 49 lakhs per annum whereas the average salary is INR 10.28 lakhs per annum. Companies like BYJU, Amazon, and Capgemini hire students regularly from the campus.

Eventually, it boils down to which college meets your needs better. 

I have friends from both Heritage Institute of Technology Kolkata and Maharaja Agrasen Institute of Technology Delhi and based on the conversations that I had with them, I will say the former is a better choice for a CSE degree. 

According to my friends, you will find that after enrolling in Maharaja Agrasen Institute of Technology, all you'll have to do is show up for sessionals and assignments. You must attend lessons or else the HOD will contact your parents. However, this opinion varies from person to person. 

Here is a brief comparison of the two institutes. 

Overall, Heritage Institute of Technology in Kolkata is definitely a better option as compared to MAIT Delhi for CSE. 

To change the stream from ECE to CSE, having an SGPA of 8.5 or more at the end of the first year is mandatory. It goes without saying that you will have to focus on your academics and try to maintain regular attendance. Complete your lab assignments and you can easily achieve an SGPA of 8.5 or even more.

Heritage Institute is now an autonomous institute so all the scores are in the hands of the faculty. The scoring rate has seen a slight decrease since the time it was under WBUT.
