The interview was very easy, no personality test, no extra test, nothing. Just casual talk and the interviewers (Mr Wun and Mr Lau) were very kind and polite. Unlike some other interviewers I have made.
I was reluctant to ask about the company's culture but the interviewers actively told me all those even before I asked.
The process went like:
1) introduce yourself
2) explain your experience
3) your expectation for the company
