What steps did you take to successfully obtain a DTV Workation Visa for Thailand?

DTV Workation, EU Citizen, remote business started few years ago.

5th May - I arrived to Hanoi

8th May - I applied for DTV for workation

13th May - status changed to pending approval

15th May - rejected (no reason given). I went to embassy and asked them personally,after she checked my document, she said - "Change an embassy". That was a bit ridiculous but I did what she said.

23rd May - I arrived to Vientiane (Laos)

24th May - I applied again

26th May - I was asked for an additional document which I provided but in better quality (passport bio page)

26th May after about 1 hour - status changed to pending approval

26th May after another 1 hour - I was invited for interview

5th June - Interview and visa approved.

Interview Question:

* What kind of plans do you have to spend time in Thailand?

* Show me account with your invoice payments

* Show me account where you have a balance over 500k

* Show me what do you do, examples of your work

Key tips:

* Dress well, be polite and elegant, very important thing in my opinion

* Take your laptop or print everything what you have provided

* Double check if your mobile apps are working to show your statements or bank balance

* Smile (yes,really), don't go there like you would go to jail, this helps in my opinion

I hope that will help other people.
