Degrees and work placement.
So many students choose degrees that they fancy are topical,or they see as an easy option, rather than researching the job market to find subjects that are in demand. Not all degrees are worth anything, a student only obtaining a 3rd, would have been better off working and progressing, rather than spending 3 years at uni.
However, any degree, demonstrates an ability to learn, that is important in the job market.
Many graduates expect to step into senior positions, but without experience they are not going to, they have to accept menial jobs with equivalent pay whilst they build up that experience.
The best programmer we employed, had an arts degree, nothing related in any way.
