Did this 2 years ago so maybe things have changed in the mean time. Here is what I know:
- the question are in the for of a couple of stories you have to do and a couple of feedback items that you have to process. These are offered to you on a sprintr.mendix.com project.
- 3 hours
- limit the objects shown to the user in a datagrid; why does one see the text of a label and someone else doesn’t; a security-violation: somebody see more data then he should;
- it’s open internet, which is very valid because that is the normal working environment of Mendix developers. Then again, if you have to search a lot, you will not be able to make it in 3 hours.
Usually, developers are able to pass the exam with about a year of experience. Get a year of experience, make sure you see enough different Mendix parts, talk to collegues about Mendix issues, do every learning path on Academy and your chances will be good. Personally, i also learned a lot from visiting this forum, but loads of people passed the test without ever using it.
