I applied through university. The process took 1 week. I interviewed at SPRG (Hong Kong) in Mar 2018
Interview
I went through a Skype interview, and it lasted for 15 mins, which was quite a short and easy interview, and I got an offer after 1 week. The whole process was quite quick. As long as you prepared the proof of your English and Mandarin ability, and some answers to basic questions, you would probably get an offer.
Undertook a written test which included a section to translate a newspaper article. Was called in for an interview shortly after the submission of the written test. The entire application process took less than a week.
The interview consists of a written test and a face to face interview. The managing director was extremely rude. She even asked about your family background, and made comments on your hobbies.
