The Sant Longowal Institute Of Engineering & Technology is an autonomous institution situated in Longowal, a small town in the district of Sangrur in Punjab. I have a known relative who is an alumnus of the institute. The following points are based on his experiences:

Pros

• The infrastructure of the institute is spread over 450 acres.
• The semester fee for a bachelor of engineering is 26,000 INR.
• The campus has a playground as well as a stadium.
• The ME and CSE department are renowned and the faculty is alumni of foreign universities and institutes like IITs.
• It has scientifically oriented clubs like Endeavour for Robotics and Aeromodelling which take part in SAEINDIA Aero design Challenge, Junkyard warriors. They participate in SAEINDIA Baja competition and Juggernauts participate in F7 racing. The teams have achieved commendable results.
• You will have a lot of time to prepare for GATE, IES, CDS, Civil Services, etc.
• Placement for mechanical and computer science is ever-improving in this institute.

There are cons as well. The institute is situated in a remote area and it would be difficult for you to get coaching classes for GATE and other competitive exams. 

The facilities provided by the institute leave a lot to be desired and so does the management which you will see in every technical institute funded by the government.
