Attended an assessment center, was fairly high pressure and the vibe in the factory wasn’t the best. I got rejected but even if I received an offer I wouldn’t work there

First stage is to do a test, then if pass you get selected for a video interview. Video interview is about an hour, is very technical, few competence questions to start then technical. Then final stage is assessment centre which is a games based and team working based assessment, no intevriew or anything Technical questions typically involve application questions regarding a distillation column or a heat exchnger, these are the most common topic choices, so need full understanding of these.

Submitted CV and did online tests, followed by online interview with 2 employees with both behavourial and technical questions. After that received offer for assessment centre at Fawley refinery which involved site tour and group activity followed by short presentation of the results of the group activity after.
