I paid for interview coaching from pinstripe solutions. Spent an hour on Skype with a specialist. The questions were not exactly the same, but the answers I prepared for the Pinstripe questions were relevant in the interview. They also helped me present myself well and avoid common mistakes that I have made at other interviews.

(I passed the interview process in November, and was offered a class date in April.)
