Standard case study, presentation, role pay just like any other AC. But the HR from Shell has a very nasty habit of getting a lot of people down for AC even when they only have few or no openings.

End result you will get a call from HR congratulating you for passing the AC then drop you a bombshell say but sorry we don't have anything for you at the moment, so your CV will be KIV and we will call you if got something in the future.

My course mate and my own interaction with their HR last year was a nightmare.
