The program says graduate trainee program not Radio Engineer. so not necessary that you must know about GSM. Unless you are a E&E engineer and looking to join Maxis as a radio engineer, then GSM knowledge wud b handy.

I figure for anyone involves in telco, it wud b nice to know what is eTOM. You can find out more about eTOM in wikipedia. and the TeleManagement official site.

Its a long shot for someone who dunno know the industry to undstd eTOM juz for interview but read the wiki and get an idea what it is about.

It'll also help (as in all graduate trainee/management trainee) program for you to show a little leadership and inniative during interview.
