One aspect of being a successful engineer is asking great questions! We shouldn't be afraid to ask questions (they are critical to how we learn and grow) but, if you follow these steps, you'll ensure the questions you ask are high quality and you can learn the most from the answers you get.

When

Ask when you've gotten stuck for a while (e.g. 20 minutes) and you're not making progress or if you've been spinning your wheels for a while.

Before you do

Make sure you've searched for the answer in the documentation, Stack Overflow, in channels (on Slack or Discord), etc.

How

Get straight to the point (skip the hello) and ask in the right place (where are the experts for this).
