Hi Putala,

Both the colleges are good in their state.

Osmania university is a state government college while HITAM is a private college.

The placement of HITAM is good , nearly 70% student get placed in HITAM. And placement record in osmania university is also very good.

I will recommend you to Osmania University because it is a state government college. So you will not face the problems after your graduation. 

Go with your interested branch and both the colleges are good.

But if you are confuse in these two branch then i will recommend you to go with ECE HITAM because ECE is one of the growing branch and in future you will get job easily by your skill.

Best of Luck !
