I applied online. The process took 2 weeks. I interviewed at Paymentwall (Hanoi) in Feb 2020
Interview
3 interviews, 30-45 minutes each, fairly standard questions. Didn't get a chance to ask my own questions though. The office was okay, people were focusing on their own stuff. Had their own kitchen.
