Is it better to do electrical engineering degree in rmit or monash???
In terms of facilities and equiptment I would say RMIT for reasons that Kanon mentioned. In terms or rep probably Monash. It all depends on the individual I guess.
Is it easy to find a job in electrical engineering field ?
Who knows...my year 12 teacher told me that 4 years ago, engineering job employment (yes electric eng included) was really high so you were almost definitely guaranteed a job however nowadays its not so high, but who knows maybe in 4 years time, or maybe next year or maybe when your friend comes out of uni the job employment will rise again.
is it better to do double degree or single???
Well a double degree implies you have broader knowledge, which is appealing to employers. I don't know about Monash, but electric engineering @ RMIT was made into a double degree (the first degree being bachelor degree and the second degree being an honours degree, so technically its a double degree).
