The maids are usually staying in the camp of the agent to wait for the job.
Routine training will be provided during the period. If they have heart to
learn, some of them possess very good language skills before coming to
Hong Kong. I learnt from those Cantonese speaking Indo maids recently
interviewed.
Mine also never come to Hk before, worked in Singapore for 4 years. She can speak & listen some Cantonese, I asked the agent, she said they provide language training for about 3 months.
