The problem you'll most likely face in terms of job search is there will be tons of other people looking for jobs too. Many of these people might have an advantage with a degree and/or can speak/write/read Chinese. Trust me, it won't just be local Hong Kong people, but also people from China as well as people from other countries. I've met a few non-Asians who can speak Chinese better than people in Hong Kong.
Because you're going for a very specific field of study, you might want to check with your profs to see if there's any opportunities for you to work with labs or university programs in Hong Kong in similar field. That would give you your advantage.
I am not sure if you can stay there for 6 months on a visitor's visa. You might need to apply for a working visa. Most apartments in Hong Kong, at least the ones you've mentioned require a 12-month contract with 1 month deposit, 1-2 month in advance, so unless you've enough to pay 3-4 months of rent up front, it's going to be difficult. Yes, there are tons of apartments in Hong Kong, but do keep in mind that because the cost of buying a place in Hong Kong is quite expensive, most people rent, so you might have a hard time finding a nice little decent one. Oh yah, most apartments in movies are considered the larger units. The majority of apartments are between 500-700 sq. ft. So, don't be expecting anything 2 spacious bedrooms with a large living room and dining room and kitchen, etc.
In regards to living in Hong Kong and Hong Kong people, times have changed. Most people just go on and mind their own business (they don't short change you unless you act like a clueless tourist). Just stick to supermarkets where you just pick whatever you need off the shelf. Stay away from the fresh food markets, cuz you'll need to communicate with the merchants in Chinese.
There are tons of foreigners living in Hong Kong and they manage well, so I don't see how you can't.
