In most cases, you have either three or unlimited attempts per question. However, this is not always the case. To avoid this problem, please note the following.
A new attempt is started automatically if the old one was not saved by you. Here it often appears that there are fewer attempts.
If the tab with the interview is left (accessed to another tab), the current recording will be saved automatically, even if there are still attempts left.
Tip: You can restart your interview at any time. Just remember that the company will see how many times you have restarted. 😌
