Need advice for BB IBD Summer Analyst position in HK/Singapore: No Chinese + Non-US School?

As a lurker of these forums over the past year who is extremely grateful for all the useful information, I just wanted to reach out to all the HK/Singapore-based WSO users for some help.

I'm currently aiming for an IBD SA position in HK or Singapore and had a couple of quick questions. (I've done some basic research and reached out to the few people I know in HK, but would appreciate more diverse perspectives.)

Quick Profile:
- ex-Japan/China/HK Asian country national
- Native in English (spent majority of life abroad) and home country language with very limited/basic Mandarin
- Top university in home country (Business Administration major, 4.0+/4.3 GPA)
- Just finished BB IBD SA program in home country (good final evaluation but no return offer--none of the very few SAs got one due to lack of headcount/TO and expected future downsizing)
- Have also done a six-month internship at home country office of a large Japanese PEF (received a return offer) and an off-cycle internship at another BB IBD in home country.

Due to the difficult IBD market conditions in my home country (extremely competitive with very few positions available; no guarantee that another SA next year will net me a return offer regardless of performance), I've decided to also try for a SA program in HK/Singapore.

In short, what I'm curious about is the following:

1. How realistic is it for a person of my background (no Chinese, non-US school) to nab a BB IBD in HK/Singapore? To be blunt, I'm more-or-less quite confident in my abilities with regards to the work/interviews, but my lack of HK/Singapore network as well as my age (I'm a senior with an additional two years spent in the military) make me wonder if I'm a viable candidate. I understand the Chinese is less of a factor in Singapore, so I guess I'm more hopeful there.

2. How much will my inability to get a return offer this summer affect my chances? While I can better explain the circumstances if it comes up in a full-on interview, it'd be hard to do so in my resume; thus, I'm considering actually removing the experience from my resume altogether (if it comes to that).

3. For the more experienced folk, do you have any career advice/suggestions for what else I could aim for given my current profile/past experiences, be it other firms (non-BBs) or other regions (perhaps outside of Asia, if that would be feasible at all)?

Needless to say, I really want to make it in a BB IBD and frankly, being unable to get an offer this summer was extremely frustrating (especially considering how many of the HK SAs in my SA class were able to--nothing against them, just two completely different market/industry environments; hope that doesn't come off as too presumptuous). I just really, really want a shot at a SA program and a shot to prove myself (I'm confident in my abilities to do well once there).

Any help/advice would be greatly appreciated. Thanks in advance, and apologies for the long post.
