Heard exactly the same story from 2 of my frens which currently in PGB and PCSB....
i got offers from Petronas last month but i decline..partly bcoz of the forced ranking environment which make me uncomfortable....
Somehow i am not convince my performance will be fairly evaluated/appreciated by the mgmt or colleagues.....
But the main reason i decline bcoz the employment term & benefit are not that attractive anymore compared to last time....
even though the salary jump is >30%, it is still not good enuf to make me resign and take the challenge (risk)....

Basically consist of normal interview, case study and skill set or personal quality evaluation based on your experience...
no role playing game, math test, english test whatsoever considering im not fresh grad (> 5 years experience)...
