I applied online. The process took 3 months. I interviewed at Shell (Lagos)
Interview
The interview was a very technical one with discipline related questions. There were also a number if behavioral questions. The interview was virtual. The panel was made up of the Hiring manager and another professional from the team.
Interview was conducted over the phone with senior professionals, apparently would-be Line Managers if one was successful. They asked technical and behavioural questions. It took about an hour. They got back after 2-3 months.
