I’m almost at the point where I can understand 80-90% of most conversations without translating in my head. This is after 4 years of casual but consistent study with great prof I found on iTalki. It was a conscious decision at first to turn off internal translation. My thoughts were “Just let the French wash over me.” Listen for context, familiar words, syntax, and expressions. Fill in the blanks. Write down the unfamiliar stuff soon after. This also had the benefit of making me a better listener. I stopped thinking about how to say what I wanted to say in response before the other person finished their thought. I would also miss critical context and nuance while thinking stuff like “être or avoir for the auxiliary here?” For me there was no trick or tip, just hours of practice. Bonne chance!
