First of all, it is important to note that Civil Engineering and Production Engineering are not the same things. Students looking to pursue courses in any of these fields are required to do thorough research before choosing and applying to a university.

Admission Cut-off:
Both universities accept JEE scores for admission. IIEST Shibpur B.Tech in Civil Engineering requires a rank around 2506-27001 whereas JU B.tech in production engineering requires a rank of 315-420.
Placements:
Thus, it all depends on the student and their JEE ranking if they want to take admission in IIEST Shibpur or Jadavpur University. Again, it also depends on the interest whether they want to pursue Civil Engineering or go towards the production engineering line.
