I applied in-person. The process took 1 week. I interviewed at SGS (Ellesmere Port, England) in Jul 2016
Interview
First I gave online a test to pass with few questions from IFIA exams , and then I gave a second test at the Central Office. Some of the questions were from the first grade school class (e.g. 5p +50p + £2 = ? ) . Two mangers interviewed me in personal.
