Exam was not that easy, included technical knowledge and IQ. After passing, I went through HR and Technical interview, were not complicated at all. After passing those I went for a 10 day assessment on site, was very interesting but stressful, had to do several presentations for readings that they gave me, and had minimum sleep to be able to complete all that was required from me daily. All in all, a very competitive process, but doable.

interview in english and i have 3 times for interview first time interview in Thai language, second times interview in English language and the last time will interview in English language again.
