You'll be asked to fill a form regarding your qualifications and work experiences, after that a photo of you will be snapped via a webcam and you'll be given a temporary ID card. You'll then be escorted to a workstation and the test which is to be taken will be explained by a polite employee. The test will have a time limit of two hours but there is no strict command on that, you can take extra time if you need to. The test consists of some very basic questions related to grammar, punctuation and spellings. Most will score good in this, the tricky part is spotting errors in an already published paper, you will have to spot the tiniest mistake and explain why, it is a mistake, merely spotting mistakes won't help.
