I did interview on June 15 and waiting for the result within this week.
The most important in interview is to be confident ( not overconfident).
Since I did the interview, I have the following advices for anyone who is in this situation.
#Be calm and don't get nervous. (if you get nervous, you can't even answer simple question).
#When they asked you questions, don't be too smart (straightforward answers, don't give explanation unless they asked you to elaborate it. For example if they asked you about your job, don't try to sell yourself like job interview.
#Every Question is based on application forms (revise all forms before you go interview). But this don't mean that all questions are from forms. Based on your application and Visa officer, the questions differ from candidate to candidate.
#Don't lie⚠ . It's normal not to remember some dates or names etc. If you don't know, just say I'm sorry don't remember that date etc. But be advised not answer all questions or most of it with "I Don't know or I don't remember".
#If you have any red-flag, prepare yourself to address them properly.
Redflags can be significant age gap between spouses, (especially if wife is older than husband) or you visited each other a few times or not all before marriage took place.
#In some countries interview is normal, for submitting new documents or police certificates etc, so don't worry too much.

Relax and pray, don't stress too much. InshaAllah one day we will be united with our loved ones.
