When Ms Li Jiayi was interviewed for a job with an escape room in Singapore, she wasn't expecting to have to prove that she could "scream like a ghost". The 22-year-old said she eventually perfected her scream and was chosen to take on the role as a female ghost in the horror-themed escape room run by the company called Inmers. As it turns out, delivering just the right amount of fear to paying customers is not child's play. Ms Li said she had to undergo extensive training to get into character.
