interview

Last week I email a company to apply for job since I'm graduating.
It's not a job, it just a engineer trainee possition.
I receive a phone call yesterday.
It's unpredictable, it's from Hanson quarray,
the HR manager phone and ask if i can went
to interview this coming friday.
Well, I'm unable cause I'm doing internship now.
Then I ask If I can change it after my internship in August.
She said YES!
Yeah!!!!
I get an job interview!!
Praise God!
if I pass the "internship" as trainee,
then i will have opportunity to get in to the company.
Help me God...
