Challenge scenario

Scenario: You're a developer at recruitment firm that specializes in tech talent acquisition. You are looking for ways to streamline the interview preparation process for hiring managers by generating tailored interview questions for various roles using AI. you need to finish the below task:

Task: Develop a Python function named interview(prompt). This function should invoke the gemini-2.5-flash-lite model using the supplied prompt, generate the response. For this challenge, use the prompt: "Give me ten interview questions for the role of program manager."

Follow these steps to interact with the Generative AI APIs using Vertex AI Python SDK.

Click File > New File to open a new file within the Code Editor.
Write the Python code to use Google's Vertex AI SDK to interact with the pre-trained Text Generation AI model.
Create and save the python file.
Execute the Python file by invoking the below command by replacing the FILE_NAME inside the terminal within the Code Editor pane to view the output.

/usr/bin/python3 /FILE_NAME.py

Note: You can ignore any warnings related to Python version dependencies.

Click Check my progress to verify the objective.

Create and run a file to send a text prompt to Gen AI and receive a response
