Toughest interview yet to come?

Went to a agency for a call centre job, turn up to be recruiting for a local bank. The location is at bedok, with shifts till as late as 2.30am. At the agency, i was explained the working hours, the pay system, the work...then came the test, a 2hr written test.

If selected, i need to go do a 3 round interview within a day. There will be a typical interview,a field testing such as doing a real customer service to a client, typing the responses in the pc as well as communicating with the client.

Sounds easy? haha..im not sure, but doing 3 rds of interview in a day already sounds tedious to me. Wasnt even sure i can make it to the interview table based on my past experience but im glad given the opportunity by the agent :) Have a feeling this sense of optimism will last me a few days then im back to reality when theres no response.

Another problem if i get hired, i didnt tell my agent abt my RT. Haha..im so deceiving. Looks like i REALLY hav to pass my ippt or else i cant commit to this shifts. Again, wats the odds for me to pass, and the odds for me to get hired. This is a double probability with prob (a) x prob (b) = total prob. Is it independent event, mayb shld be prob (a) + prob (b). Y didn't i tell this to the agent, simply i wont risk killing my chances. i have to pass...regardless i got it or not. Can i..
