Thank you @engray, I have a feeling you will hear soon about yours as well. I noticed my background check is still in progress, is this normal to be invited for a test when background check has not completed yet?Congrats, usually the email comes in a few days before the start of test window. There is no need to "book" the test, once you are ready log in within the test window and take the test.
Please let us know when you get the actual email, and when you take the test. Congrats!
