This actually looks more like a race condition in LogInfo for this demo. IT should have printed out an example job, but this is an example console output in the ESP-IDF 4.2 PowerShell window:

14 495 [iot_thread] [jobs_demo.c:833] [INFO] [JobsDemo]
/*-----------------------------------------------------------*/

The Jobs demo is now ready to accept Jobs.
https://docs.aws.amazon.com/cli/latest/reference/iot/create-job.htmlJobsDemo]

 - print          ] [jobs_demo.c:843] [INFO] [JobsDemo]  key.
   Logs a message to the local console. The Job document must also contain a "message".
 - publish        "action17 495 [iot_thread] [jobs_demo.c:846] [INFO] [JobsDemo]
   Publishes a message to an MQTT topic. The Job document must also contain a "message" and "topic".


   For example: { "action": "publish", "topic": "demo/jobs", "message": "Hello world!"} will cause
 - exit           to be published 19 495 [iot_thread] [jobs_demo.c:854] [INFO] [JobsDemo]
   Exits the demo program. This program will run until { "action": "exit" } is received.

Ah, it looks like the carriage return at the beginning of log messages isn't overwriting the current line. It's a hacky way of suppressing the log message header.
