HR called and set up the interview date, did the interview with Team lead, well delivery manager and HR present. Got a phone call the next day and was told to expect the offer letter. The offer letter came I accepted, signed the necessary papers and resumed on the agreed date. Did some medical test, vision and hearing test.

two telephone interviews. First was a situational interview (give me and example of a time when you did x). Second was the same except it was kind of a role play. They asked if I understood Shell's life saving rules. They asked how I would react to certain rig based safety situations. For example, what would you do if the driller wanted to drill ahead with no secondary retention system in place on the top drive. The opvious answer is that you should stop the job.
