I am also a Business Analyst, in IT field. Got offered to interview with HSBC through headhunter. Previously interviewed with them once (through Capco) and got the job, but I turned it down.. as I don't want to go through Capco.

Heard their project mostly deal with HK/Taiwan/China.. thus the requirement for Cantonese/Chinese speaking.. and you may have to work according to the country's holiday schedule
