You can definitely try and apply for it. IIIT Delhi is also feasible for you or you could also go for NSIT Delhi / DTU / IIIT Delhi. You might end up with ECE or IT at NSIT Delhi, Software or IT at DTU, ECE or CSE at IIIT Delhi.

• Your future completely depends on the marks, your aggregate percentage/ GPA, PORs, and skills in your resume once you graduate. 
• Probably every college in India has good placements in CSE /IT/ Software Engineering but if you take a lot of interest in programming or developing apps, OS, big data, security, ML, AI, Computer vision, etc, you will definitely bag a great MS/Ph.D. admission or even a well-paid reputed job. 
• You just need to put lots and lots of effort into this and not play games with your college percentage or GPA. Try to maintain it above 75%.
• Top companies like Google and Facebook, regardless of your stream, are open to all branches. They just see your coding skills and overall repute. But many companies only allow CSE/ IT graduates to appear, some of them are strictly for CSE.

If you are not a CSE/ IT student, getting a coding job will be hard but not very challenging. Only if you take programming seriously, you will be selected in Google or Facebook which is equally tough.

You could even have a try at Hackathons, learn, practice new programming languages, web development, and basics of graphic designing along with the complete back-end work. Try to make some interesting apps, contribute to open source and you will see budding opportunities ahead of your way. Try not to play with the college percentage/ GPA because they decide which companies you can sit for.

To know about the procedure or hardness to change/upgrade your branch, you must first know the prerequisites for the same. There are two factors based on which branch up-gradation depends and these are-

• Number of available seats
• Aggregate SGPI of students

Now, seat availability is a crucial factor because, the more the number of seats, the more will be the chances of branch up-gradation. 

Since IIIT Allahabad is shutting down its dual degree programs, the number is supposed to reduce as the branch up-gradation will be restricted to ECE-IT conversions only.

Now the other factor i.e. SGPI, 9+ can be considered safe for branch up-gradation from ECE to IT. It might go as low as 8.7 but to be safe try to score 9 SGPI.

If you compare IIIT Allahabad placement cell with MNNIT Allahabad, then go for IIIT Allahabad. According to some of my friends studying there IIIT Allahabad would be a better career choice. 

The following table will show you the placement record of IIIT Allahabad or MNNIT Allahabad.

IIIT Allahabad has a better placement cell. One of my relatives studied at IIITA and suggested that its alumni are wider and stronger. IIITA also keeps up with the pace with industry and market needs. 

IIITA some of the top recruiters are Google, Adobe, Accenture, Amazon, HCL, IBM, LinkedIn, Expedia, Wipro, and many more. The highest salary package offered to IIITA students is INR 43 LPA, while the average is INR 20.83 LPA.

Therefore, if you are considering taking admission between IIIT Allahabad or MNNIT Allahabad, then choose the former, as its placement cell is better..

It depends on your future plan. If you want to teach, then go for an integrated Ph.D. degree instead of an MTech from any institute. It will save you 1 year.

However, if you want a career in research then do a Mtech first and then go for your Ph.D. You can get your Ph.D. from other better institutes like some IIT.

An integrated Ph.D. will take a minimum of 6 years to complete. Getting the award depends a lot on your performance and your mentor. If your mentor is happy with your performance, you can get your degree done within 5 years too.

On the other hand, doing an M.Tech and a Ph.D. separately will take at least 7 years.

So, consider all these factors and choose what’s best for you.

Since you know what you are looking for, it becomes quite easy to segregate categories for you to choose which place you want to go. Do all-around research and look at various categories like crowd, course curriculum as well as the faculty before making a decision. Here are some points that may help you out.

Faculty: One point where IIIT A might lag is the faculty. Being a top college, you might expect it to have some of the top-notch faculty in the country. However, it is more of a mix of government college faculty with some average teachers and others that are really well-versed in their subjects. IIIT D on the other hand has better faculty who have a rational approach to the subject of computer science. IIIT D definitely tops here.

Course Curriculum: You will find some of the best course curricula at IIIT A. You will be introduced to the subjects of computer science right from the very first semester. A major plus point is that there are no interdisciplinary subjects like ED that will be included.

Crowd: As far as crowds are concerned, both places have the same crowd. IIIT A might be slightly better as they do not hold any state-based preferences or quotas.

Coding Culture: The coding culture at IIIT A is one of the best in the country. This college is the pioneer college that represents our country in some of the most major competitive coding platforms. Just recently, 12 students were even selected for GSOC from IIIT A. IIIT D is still in its nascent days as far as coding is concerned.

Infrastructure: This is one point where both colleges are at par with each other. Both are good as far as basic amenities are concerned.

Lastly, you should know that IIIT A is a college with a national reputation. It will definitely give you the upper edge when you go for your masters. This is probably not the case with IIIT D. However, if you are looking for good faculty and a city atmosphere, go to IIIT D.
