Which would be better, “Civil MNNIT Allahabad or Civil NIT Surathkal?” I am a North Indian.

It is difficult to shift to a location that is far away from home. As a North Indian who was faced with a similar situation, I can completely understand your hesitation in choosing NITK.

Talking about this branch, the placements of Civil are comparatively low, irrespective of your college. Even in the IITs, a number of Civil students remain unplaced. But overall, the placements for Civil are slightly better at NIT Surathkal. NITK also has better infrastructure and a private beach.

But if you plan to prepare for UPSC or GATE, like most Civil students, MNNIT is an ideal choice. MNNIT students secure top ranks in these exams. The environment of MNNIT is ideal for the preparation of competitive exams. I am not aware of the environment provided at NITK for competitive exam preparation. 

Both MNNIT and NIT Surathkal are renowned colleges. Both are good choices. You should choose between them based on personal preference. I would also recommend you approach some seniors from NITK to learn about the lifestyle and eating habits over there. Try to find out if the place will suit you or not.
