I applied online. The process took 3 months. I interviewed at Kantar (Kuala Lumpur) in Jan 2018
Interview
Almost an hour but I enjoyed the almost casual Q&A nature of the interview session.
Interviewer was generally very interested in getting to know me and my skills / experience.
I applied via their website and got a text scheduling an interview fairly quickly. If you pass this, they email you to schedule your case study presentation (they give you the data tables) and panel interview. It took a week for them to get back to me with an offer.
There was first basic aptitude quiz and the shortlisted went to the group discussion. After a week, they called us for a coding test, technical interview, team game and finally HR.
Interview questions [1]
