Applied online 4 weeks ago and received an email inviting me to attend an assessment day at their office in Gatwick. Started the day with a brief presentation about the company and were then given the opportunity to ask a Field Engineer a number of questions. Seems like interesting but very demanding work. Then had to sit 3 tests, the first of which was a relatively straightforward logic test which I think everyone seemed comfortable with. The had to sit two more tests which were unlike anything I have ever done before, and were very difficult having 20 questions and a 15 minute time limit. I guess everyone passed though as no one was asked to leave. Then had to give our individual presentations, relatively straightforward however I would advise anyone that is applying for this job to make their presentation as interesting as possible and not just fill 5 slides with writing, as it can become a snore fest otherwise. After this we had lunch. Then had a group exercise in the afternoon which involved building a structure from paper and sellotape that could support the interviewers phone, and the winning group was the one which was tallest. This was surprisingly fun and a nice change from the high pressure morning tests and presentations. After this had a half hour technical interview, where they basically went through my CV and asked a few engineering based questions. Then a half hour interview with HR in which you had to assemble a valve in under 5 minutes (or try to), and then answer bog standard interview questions (why do you want to work in Oil and Gas etc). Overall was an enjoyable but slightly exhausting day.
