Applied through recruiter, had a recruiter screen then backend tech screen. Everyone was kind, and got a prompt response after each. I was interested in a frontend position but was given a backend problem.

You're given a starter kit with a helper that simulates a microphone by slowly streaming an audio file.

Your task:

• Asynchronously consume the stream
• Batch the small audio pieces into chunks of at most 30 seconds
• Send each chunk to a stateless HTTP transcription/formatting backend
