usually company no tell u.
but sometimes they tell u.
i was, 2 yrs ago, rejected by IMCB and Rojah & Tann and MOE,
IMCB no telled me, later i write to the boss interviewed me, he told me no offer to me;
Rojah & Tann write me an email to tell me,
MOE print me a letter to tell me.
usually we apply as many companies as we can, and just wait for the offer letter but not rejection. god luk.
