Interview
The interview had general personal questions with some problem solving steps. Not something you would inherently need to prepare for, they are just looking for how you think to a solution to the problems. Experience in HAZOPs, LOPA, NEBOSH would be a plus but if you don't know what this is, read up on the process so you understand what this is and why it is used in the industry.
