Held in conjunction with NTUC's Employment and Employability Institute (e2i), the recruitment exercise saw applicants attending a career briefing and one-to-one interviews.

They also went through tests which checked for colour blindness, and how well they could do mental arithmetic. This was to ensure they are suitable for jobs that may need them to calculate and count winnings on the spot, or identify different coloured chips.

But the integrated resort is not just looking for croupiers. Various other positions, from slot assistants, pit supervisors to surveillance technicians and cashiers, are up for grabs.

About a third of them are managing or supervising positions.

Marina Bay Sands has been tight-lipped about the number of applications, and would only say that casino jobs' applicants have numbered 'thousands'.

But e2i has estimated at least 3,000 more will be screened in the next three weeks over five sessions, with more to come as the applications continue to flow in.
