Hi,
There will be no industry specialized words. I saw some at BCG Online test, but there was a page with the description for each term.

These tests aren't trying to test your specific knowledge of any industry - therefore, you are very unlikely to face any industry-specific terminology in the test. You may face some generic business terminology (e.g. gross margin, break-even).
If you did encounter a word/term you didn't recognise during the test, the invigiliators won't be able to help you, so you will have to take your best guess on what it means based on the context of the question.
