1. HKU MEcon is in the business school. But actually, it is quite clear that they are not enjoying the career service of the HKU business school too. Limited business school are for MBA, who had paid a high tuition, and undergraduates.
2. Comparing program by input quality is generally not a good idea, at least not a major one. Tons of other factors.
3. It is not reasonable to compare cohort ability based on English ability. Does the higher average IELTS scores in the art faculty over the engineering faculty implied that art students are better than the engineering one.
4. Technical role in the industry are not limited to BB and HF. and actually there are MSc students getting interview and offers from that (for sure, it is competitive are far from common, just like getting a good offer from any university and major)
