The whole process took about 2 months+ and all the interviews were organised by HR in Hong Kong, who never got back to me regarding the result after the final round. First round was just a phone screening done by HR and then they organised phone interviews with directors in HK and US once every week. I was invited to their regional office for the final round interview done by a group of people in the US. I followed up with HR in HK after the final round and they never responded to my email. Even during the interview process, they have ignored my email and I find that they are VERY unprofessional. It was a complete waste of time.
