Bachelor of Technology [B.Tech] (Civil Engineering) From NIT Trichy, Tiruchirappalli

I am assuming that you are asking about core civil job profiles. According to my friend at NIT Trichy the placement record for the Civil Engineering branch is quite good. Here is the placement trend for the branch. 

According to the placement highlights of the past few years for Civil Engineering the highest CTC offered by the recruiting companies is around 17 LPA. During the placement drive 2020, the average package offered was INR 6 LPA.

More job offers are made to the civil engineers from companies such as Oil and other related companies. The salary package offered by a few conglomerates like L&T varies from INR 6.2 LPA for IITians, INR 5.11 LPA for NITians, to INR 3.6 for Local/Private Colleges. This is the general trend. It varies depending on the academic year. 

If NIT Trichy is your only option, then you can go for it. But for Civil Engineering infrastructure can be a vital factor. 

The budget that usually is allocated for infrastructure incorporates buying lands from peasants to fund the research later on with a low-cost housing or environmental impact assessment. 

If you have chosen Civil Engineering, based on your electives, you could opt to specialize in Hydraulics engineering, Structural engineering, Environmental engineering, Building materials, Geotechnical Engineering, Transportation Engineering, Construction Management, Infrastructural engineering, and other relevant disciplines. 

It is best to get familiar with the topics briefly noted above. Based on your knowledge and expertise, choose one (or more, if required) of the many specializations and then do a brief research on the basic amenities, like faculty strength and similar aspects of NIT Trichy. 

However, in terms of academics, NIT Trichy is an excellent choice.

Some of my friends studied at MNNIT, so I might be able to answer your question. It is suggested that you choose Mechanical at MNNIT Allahabad rather than Civil at NIT Trichy.

Your branch of choice is more important than your college preference. In terms of opportunities, Mechanical Engineering has a slight advantage over Civil Engineering

Mechanical at MNNIT Allahabad has a consistent placement record. Mechanical students receive more job offers than Civil Engineering graduates. PSUs often choose Mechanical Engineering graduates.

Finally, everything depends on your interest and choice. So think wisely and then make any decision, because this will be the building blocks of your career.
