Just to update for those who are interested.
I'm a fresh graduate holding a BEng (Civil and Structural) from University of Melbourne. Applied for Shell in March but found out the recruitment process is super long. So as advised, I took up employment elsewhere (highly recommended) with AECOM in KL for the time being. Position that I was gunning for were discipline engineering, project engineering and well engineering.

Here's my SRD progress so far.

Once you've completed the 1st competency test, you should receive a 2nd email stating the 2nd part of the online test. Within this email, a link to the second test will be provided and you have to complete it within a week of receiving it or else they will assume that you wish to withdraw your application. All the best!
