EDIT: I know 2 weeks is a short time period but in Asia employers tend to evaluate rather quickly. Plus due to financial concerns with small businesses a 'highly-paid' (relative to other jobs etc) employee can be an ongoing concern for them.

As I can be quite sensitive in general, in Asian countries, especially small local businesses (less than 50 people) or even large companies (hundreds of people), employers can be very tight-lipped about their satisfaction with your employment **and also what exactly they want you to do**. Or even what they really expect.

My personal opinion is that this is a Chinese/'IndoChinese' cultural trait where outright forward verbal and especially written feedback and discussion is very carefully or cautiously phrased. 

I am half-Chinese and spent my childhood and periods of adulthood in South East Asia.

Part of this tactically is a "gambling" mentality as in "let's see what I can get out of this employee/employeer" which obviously is not limited to any specific culture, though it is common in Chinese culture - whether malicious or not. This is a cultural fact and let's not get politically correct because directness is the topic of my question.

Nowadays larger organisations do have KPI, reviews and so on. However smaller businesses or certain departments of companies appear to have the above wait-and-see approach or what some developers or managers call "subtle control" since outright control would cause an employee to leave unexpectedly.

Being predominantly Western-educated and having Western work experience it is hard to extract information on what exactly they want, and what exactly they require since I am now considered well-compensated in my current new job.

I have tried enquiring during these first two weeks what their expectations are, what the goals are and so on but I suspect there's still a high-level of restraint from the key managers/owners. Short-term goals and tasks have been negotiated adequately but my concern is how to I obtain more information over time - in a relevant, professional, industry-standard (tech company) way? This would benefit the business and obviously myself over time because second-guessing at every turn is stressful.

Yes I could be more "uncaring" but I am wondering if any of you know other approaches.
