That's great!

You can start by checking out job platforms like Jobstreet, Wobb, Glassdoor or LinkedIn and applying to the companies there.

All the best!

Hi Furqan, I would suggest you to prepare a short and catchy CV first.Then start spending time at job platforms on daily basis or once in a week atleast. Apart from just sending the CV, it is also important to follow up with the applications that you have sent. It would be really great if you could send an email or drop a call to those companies that you have applied for internship to follow up on the application. That would show your interest on the position. To add on, Petronas mostly accept the application through their website.

Good luck!!!
