TIP #1
Ideally, decide on 2-3 general questions in the first interview, and if you have made it to the next round, you can ask more specifically.
TIP #2
Do your research on the company! Avoid asking questions that could easily be answered by a quick look at the company’s website.
TIP #3
You shouldn’t be too passive, but also be careful not to shoot yourself in the foot by asking certain questions actively (salary, employee reviews, holidays, etc.).
