The screenshot contains Python code using asyncio, but no explicit interview question or task is written in the image. If the task is implied, it might be related to identifying or fixing issues in the asynchronous code. Here is the code from the screenshot: ```python import asyncio async def func_1() -> None: await asyncio.sleep(2) async def func_2() -> None: await asyncio.Sleep(3) async def main() -> None: await func_1() await func_2() if __name__ == "__main__": asyncio.run(main()) ``` Potential implied task: Identify and fix any errors in the asynchronous code.
