I also Have a P-Tec degree and have taken the PTEX with a score of 96. I’ve tested for Ineos 4 times over the last 3 years. Twice during COVID because they started demanding the vaccine and everyone was turning down the job. I’ve never received an invite to interview. They always send me an email saying I didn’t score high enough to move on to the next round of the selection process. I can tell you this, The test is not that difficult. I can guarantee I’m getting all answers correct on the English, Math and mechanical aptitude portions of the testing. However, they send your personality portions to a third party company, at least that’s what HR told me, and that score is what they are really looking at. Just a side note, I spoke to someone that is a tech 5 at Ineos and he told me it took him 7 years to get on at Ineos. Good luck. But I wouldn’t sweat the tests.
