Most helpers are only able to go for face-to-face interviews on their off days. However, some are available on weekdays and Saturdays as well, should their current employer allow them to go out. They can also be available at the end of their workday for a Whatsapp or video call.
On average, it takes employers 2 weeks to browse profiles, conduct interviews and decide on a helper to hire. If you have clearly determined your needs and expectations in the beginning of the hiring process, you’ll have a much better chance of success.
As the turnover rates of the helpers can happen quite fast, do schedule interviews with helpers you are interested in as soon as you are able to.
