I applied online. The process took 2 weeks. I interviewed at Ipsos (Ho Chi Minh City) in Aug 2015
Interview
Firstly, you will be contacted via phone by HR and they will give you an appointment for the HR round interview.
The HR interview is quite easy with ordinary questions like why you want to work for company...
Smooth and fast. There were three rounds. First one was basic introductory round the next was with immediate manager and final technical round with ED. Overall it was smooth and fast
