I have applied for 2 year diploma course in Humber and Seneca college..

These are the courses I applied for..

Seneca: 1st. Electronics Engineering Technician - Computers
2nd. Computer Networking and Technical Support
Humber: Computer and Network Support Technician

Now please tell me, which college is better at Computer/Technology related courses, also, which college can get me in fast job after graduation?

So much about getting a job will still be you, and the impression you make on a interview.
Humber seems to brag more about finding jobs, but that is in all areas.

Meaning I shouldn't be worrying about the Education in both schools and should look for the "closest" to my house and other factors?

What are the other things to look out for, thanks!

Seneca is very well known for its Computer Studies and Electrical Technology programs. There is co-op in all the programs you have been offered. I suggest you visit the facility of Eng. Tech at Newnham Campus, 404 and Finch, to see our labs, or the Seneca @ York Campus where we offer the Computer Studies programs. Our tour site is www.yourfuture.senecacollege.ca
