Good agent will not sell the same maid to more than 1 customer simultaneously. They will reserve her 1-2 days for consideration after interview or trial. After this period, agent will give u a final notice before release her file to other customers. I personally accept this because the maid has only 14 days “life” in HK to find new ER after release, they can’t afford longer time since the chance of finding another ER get smaller and smaller as time goes by. I think 試工 is very important but 1 full day is enough. I mainly pinpoint on her initiative on those small areas that I haven’t told her and attitudes towards different people. I won’t take those agents who are too pushy and do not encourage 試工.
