what interview? To sweden there is only interviews if you want to get a resident permit by then you need to either have work in the country or a connection like marriage.
And ofc you need to go there in person mostly to VFS that handles the tourist visa applications for most of the schengen countries not the embassies. When you make a visa to thailand you need to visit the embassy of thailand aswell...
Last time i helped one with a visa to sweden a single woman.. was copy of passport, founds in bank 495sek/day. Paper that she can be off work. Insurance cover $1m. Booking confirmation to there and back to thailand. And a letter of what she was going to do and why and the migration paper filled and signed. Done two weeks later got it and collected her passport and went to sweden then the rest of Europe. Its about 15min work and some hours to turn it into VFS and then just wait.. so I don't understand how you guys can say its hard.
