The 5%ers interview questions

Seemed like a forced interview. There was an HR and maybe a HR intern. After HR asked everything she wanted, she asked if I had any questions as I did. In the end she offered her intern to ask me anything where she also asked me if I had any questions. (We all know saying no to such questions is a red flag). But I had to say no since I've already asked everything I wanted. We did not come to agreement because the salary offer was $5/h gross which in my country after paying taxes is a minimum wage.
