This kind of test doesn't imply any 1-1 interview, nor technical verbose definition, nor any multiple choices, but is rather mainly an online simulation test aimed on your understanding of automated testing. That's what the test is mainly about. The idea is being able to generate 50 successful tokens in a row through username&password login. So in order to get a successful token, you'll first be asked to find a way to generate proper username and password combination to login. A hint... the username and password are the same and are mainly composed of four identical numbers series... At least the combo worked in my case... The next catch is to override a maximum of 10 tries. When you'll reach the 10th you'll probably hit a message saying you've been detected as a bot! A way to override this issue by clearing the cache at 9 and also restarting same session with different fake Selenium drivers and proxies. As proof of success, I also added a line of code enabling to take a print screen jpeg image of each successful token and save it on temp directory, just to make sure. So that was it.
