HOW TO USE IT

Download the numbered topic documents individually and open them in Microsoft Word or another DOCX-compatible editor. Start with 01 - Application Tracker Guide and use the separate Excel tracker. For the hands-on mini-cases, download and extract the Exercise Files ZIP, then follow its START_HERE.txt. Choose your next step, track your applications, then practise answering aloud before you check the answers.

Personalise every template with your own experience. The fictional examples are for learning.

The SQL + Python workbench is free and open to everyone. Copy any code you want to keep before refreshing.

This is a self-paced digital download. Updated weekly. Check this listing for the latest version.
