CPPIB/Orbis/Blue Crest/Temasek

Hello everyone, I'll be graduating next June and am interested in applying for AM/LO/HF internship/grad programmes in London. I was wondering if anyone could share their experiences at the following 4 firms: CPPIB, Orbis Investments, Blue Crest Capital Management and Temasek Holdings as I feel there is not much information regarding these few firms and I would like to find out more before applying.

I would greatly appreciate it if someone could share how: i) life of an intern/grad (responsibilities, hours etc) ii) reputation iii) remuneration iv) prospects for the long-term and v) culture compares to that of the large AMs like Blackrock, Fidelity, Wellington etc and BB AMs. Cheers!
