RIVRS interview questions

I received a call from a recruiter, and they asked me to complete a Roblox-related test. It took me a full day to finish it. Three days later, they invited me to an online interview with two French interviewers. They asked many questions about the test. One of them was very impolite and made me feel uncomfortable, but I still remained polite and completed the interview professionally. They told me that the result would be sent within 10 days. Later, one of them messaged me privately and said that the process would take longer because of the holidays. However, after one month, I still never received any result, even after I followed up with them. It does not matter whether I get the offer or not, but the way they handled the process and treated candidates was very unprofessional. I know they are a startup company, but the way they work is really bad. Based on this experience, I believe their company culture may also be very poor.
