There will be usually 5 rounds of interview.
Self-introduction and one same question for all candidates.
The wannabes will be asked to enter a room in groups of 10. There are usually 2 interviewers. Each candidate will be given 2 to 3 minutes to do the self-intro and answer a question. An example of the question may be like this: Which celebrity would you like to be and why? Notice it is an open ended question and so you must not forget the “why” part.
After passing the 1st round SIA will subject you to a skin check. They want to ensure you have a reasonable good skin. Remove the tattoo if you have one that is conspicuous.You will do the "reach" test unless you are conspicuously taller than the minimum height required by SIA.
Around 6 candidates will be selected and will be put into 2 groups. There will be an introduction of your partner to the panel of 2 interviewers. There may also be group discussions of topics given and the reading of selected passages by the individual candidate. The interview may take up to 40 minutes.
If you get through the third round you would then face 2 interviewers in this round. This is like a chit chat session. Also they may ask you questions from what you've stated in your application form. You may be tested on "calmness" or "coolness" and "maturity". Do not react negatively even if the interviewers try to provoke you. Stay calm and smile.
The 5th round: The kebaya/skin check round.
Girls will be asked to wear the kebaya and walk a little distance so the interviewers could assess your poise and way of walking. For the men, they may be asked to walk.Then there will be a thorough skin check. They will look out for blemishes, visible scars,tattoos etc on your hands,face and legs etc.
This round may be conducted on the same day or another day.

This video teaches the candidates on how to survive the first round of the SIA cabin crew interview. It is dubbed by me as the "killer round" as it is the first most difficult hurdle to cross. If you pass this stage of the interview, your chances of passing the rest of the interview would be relatively easy.
