You may have either Online Test or Written Case (pls check with an HR)
I've uploaded some samples here:

As for particular recommendations for online test:
- Try to find as many people in your country as you can who have done the test. Ask them for the topic, industry, and questions they remember. For example in one of the countries there was a test about airlines and reading a couple of articles / company reports / wikipedia articles with industry terms could significantly improve performance
- Try to practice tests with strict time-management. McKinsey PST from the official web site and all mck and bcg -like tests you can find online
- Additional resources can be GMAT Integrated reasoning from the official guides and apps if you feel that you are not p[erforming well
- As far as I remember calculator is allowed on BCG test. Make sure you know how to simplify calculations and use it fast
The best way to prepare for the written case is the following:
- Check if the calculator is allowed. So far it was. If not - you have to train mental math. I posted the main tips here: https://www.preplounge.com/en/consulting-forum/tips-to-do-big-multiplications-in-my-mind-726#a1422
- Prepare for a regular case interview - it helps a lot. Basically, prep lounge website is about it
- Practice making slides. Look for publically available MBB presentations for reference. Good books are "Pyramid Principle" and "How to make it with charts"
- Practice reading cases fast and prioritizing the information. I found useful two sources:
- Written cases you'll be able to find in google or in case books. I've seen a couple in "Vault Guide to the Case Interview" and "Insead Business Admission Test"
- Harvard cases - either buy or try to find online. You can find a couple of MIT cases here for free: https://mitsloan.mit.edu/LearningEdge/Pages/Case-Studies.aspx Unfortunately free cases don't have the prep questions.
The appropriate structure for BCG written case is:
Slide 1: Context, Objective, Recommendations
Slide 2-4: Analysis (Usually 1 slide with a table, 1 slide with graphs and 1 slide with pros and cons)
Slide 5: Next steps or risks & mitigation
