Yes there are a lot of useless degrees like arts, there is no job for arts.
However you did commerce, you should have been able to find a job. You can't just aim for the top 4 firms only in the country lol.
I did Engineering, i didn't get a job straight out of uni, it depends on when companies are hiring. Most good degrees students will land a job with a year.
Landing a job straight out of uni within the first 3 months is highly unrealistic expectation. If 70% are getting work within that time frame then fmd, that is pretty damn good.
