The phrase "What you think about me" in Hindi can be translated as:

• "तुम मेरे बारे में क्या सोचते हो?" (Tum mere baare mein kya sochte ho?) - when speaking informally to someone.
• "आप मेरे बारे में क्या सोचते हैं?" (Aap mere baare mein kya sochte hain?) - when speaking formally or respectfully.

If you want a shorter or more casual version, you could say:

• "तुम मेरे बारे में क्या सोचते हो?"

Let me know if you want it in a different tone or style!
