cron job

Transfer the ownership of your TestnetConsumer contract to your node
In remix, click the drop down menu of the TestnetConsumer contract, and paste your node address in the transerOwnership box and click the button.
Send LINK to the TestnetConsumer contract.
Ensure there is ETH on your node.
In the node GUI, click on New Job and paste the JSON blob below.
Make sure that the 'address' is your TestnetConsumer address and the 'dataPrefix' is 0x followed by the 256 characters from your testnet transaction.

In 10 minutes, check to see if any jobs have turned up and find the tx hash on etherscan to see whether or not they have failed.

amazing. I'm a bit confused as to where I find this "256 characters from your testnet transaction"
what is that referring to exactly?

did you follow the 'Fulfilling requests' section of the docs?
When you test your node with the requestEthereumPrice transaction, click the etherscan link and scroll down
you should find something that looks like this
Function: requestEthereumPrice(address _oracle, string _jobId) ***
