The initial phase starts with an aptitude test which can be done online. They will then select shortlisted candidates for a face to face interview followed by a final assessment center.
I applied online. The process took 4 weeks. I interviewed at Givaudan (Singapur) in Apr 2016
Interview
Call by HR, face to face interview with HR, SHL test, then invited to an assessment center (where I got eliminated). After an assessment center, there should be a panel interview with the big shots.
