I have a friend studying at IET Lucknow from the Civil branch. I will not be able to tell you about HBTI but I can guide you in the case of IET.
The following table shows the placement statistics of both institutions:
Particulars | IET (Mechanical) | HBTI (Civil) |
Placement percent | 30% | 45% |
Highest salary | INR 11 LPA | INR 9 LPA |
Average salary | INR 7 LPA | INR 7 LPA |
Top recruiters | Tata, Hero, Naini Papers | Hindalco cement, Ambuja cement, LnT |
Being from IET is also not bad, though not comparable to being from Harcourt.
