Hello All,
Do not pay anybody for materials for the test. I wrote it 2 years ago and I did very well. I wouldn't be able to help you out with info on the interview or payment or other things involved because I didn't go for the interview or take the offer because I already had a scholarship to go abroad and didn't want to spoil the chance for others. I can tell you it is a very good course because I know other people that got the offer and did the course. It is very competitive as well so study hard. It is pretty much an aptitude test and basic engineering questions (all disciplines). There are also some odd things in there like English, biology, current affairs and what not. The main thing against you is the time. I can almost say it is impossible to finish within the time limit (but there are some extra-ordinary people that just might, who knows). If you do know a question, move on. There might be others much easier to you down the line.
Anyways, i decided to chip in because I can see people trying to scam with materials that aren't even relevant. I will attach a link to materials that I can confirm are relevant and will help you out in this test. I hope the link works for all of you and I wish you all the best.
One more thing, if you get in. I know you might have heard it is automatic employment into Total and what not. That is not exactly true, it depends on the situation in the company at the time. Spread your tents, The IPS degree is respected by all employers in the industry. Don't believe Total will absorb you immediately, they might, but don't put your eggs in that basket only. It is a bad gamble. Once again all the best. Find below the link for the books. let me know if you have any issues with the link. I doubt I can be of any more help being that I didn't go to IPS.
