777driver06 - an accurate guide at last! The fact that SQ have invited you to attend the selection process, is an indication that they have assessed you as potentially fitting their requirements. The process is then a formality for you to prove that your experience, health and piloting skills are indeed as claimed and to the standard required.
I enjoyed my time with SQ and found them to be a well-structured company and honourable as well.
There are many who claim otherwise, but that is my opinion.
There are also many who enquire, but fall well short of the minimum qualifications, but are more interested in the "cash-in-hand" tales. Time wasters!
