I have finished ES Engineer Training. Where can I find link to download PDF guide?
You can access to the material in your learner dashboard at learn.elastic.co. You can:
Step 1: Login to the Elastic Learning Portal at https://learn.elastic.co/. Click on the Elasticsearch Engineer - Virtual title found on your Dashboard.
Step 2: Select the CONTENT tab, and download the available files.
Hope this helps,
It was not specified to be an ondemand training. In that case, if you scroll down the page, you should see the section "Additional Resource: Download PDF" and from there download the material for every module.
What about lab guide? Is there a PDF version?
Unfortunately there are no Labs instruction in PDF format to download, those are only accessible in HTML format from the Strigo lab instance.
