Selected for 1st round of interview:
1) Required to visit site in person
2) Required to do a test paper (depend on your technical knowledge, but whether they mark or not I am not sure)
3) Interviewed by panel (Process + HR).
I rejected 2nd round of interview because the salary is not within my interest (i.e. about SGD 65k+ including all allowances/bonus for highest/most senior technician position)
