First you will be asked to submit your CV through email. If you successfully pass the CV screening round, they will invite you to their headquarter for a test. I was late for the deadline actually but as they had many candidates sending application after deadline, they organized a specific date for us. Hence your application process might be a bit different.
There are two tests: English test and logical reasoning test. Both of them are easy. After that you will be marked and invited for a group working to solve a case study, then each will have chance to present his/her ideas. If your performance is good, you will then enter an interview round. There are two managers from the functions that you made choice from the beginning.
I was selected for the final round: assessment center but I didnt attend due to family business. It was a pity as I really love this company's culture
