It was conducted fully in english, but you may explain some questions in Indonesia if you fell more comfortable with it. The HR interview will ask you to introduce yourself, experience, your reason why you apply, your expected salary, when will you can work. The user interview will ask you the same thing but a bit more detail. You will also get asked about how you work in daily, your habit, your strength and weakness, business and logic questions. All questions are in english so be prepared especially when you are gonna answer a technical process. The user is friendly and will not judge your answers.

The process was quite typical which involves a HR screen, technical test and some interviews. The HR associate also got my name wrong and was late for 15 minutes due to overran the previous interview.
