^I just wanted to add a few things, hopefully it will help others too. I applied for the tourist visa with no relative nor a friend to visit so it was a 50-50 chance but I thought might as well apply if I wanted to get approved (or at least try).
When I entered the embassy, I was asked to line for finger print scanning. After this, a number was assigned to me. On one window, I was asked to show my passport and if I remember it correctly it is the same window where I submitted new pictures because the scanned ID picture in my application wasn’t clear enough. After this, I was asked to wait for my number to be called for interview. Seats are in rows and facing the interviewers. I chose to be seated near where the interviews happen so I can observe at maybe learn from others on how to answer or what to avoid.
If employed, usual question is the net and gross salary asked separately. If they asked you about the gross salary first then ask you the net pay in the middle, make sure it isn’t interchanged because it may trigger further questions like why are gross and net pay the same, if there are no deductions or tax, etc.. Answer what is being asked, not divulging more than needed and be truthful. If the applicant has traveled outside the country, be prepared to be asked for further details like where was it, cities or places visited, date and how long.
In my case, I was asked about pay, employer, why I wanna apply, traveling with whom (in my case traveling alone), where I wanna go and why I am applying for a visa. I wasn’t asked for any additional document, just my passport. Good thing they didn’t ask for any proof of property because I have none and I have minimal savings (less than $2000 at the time of application).
