XR specific tech interview

AR / VR / MR / XR

Explain what is AR / VR / XR / MR, how are they connected? Why would you choose one over another?
Your client is saying "I want a HoloLens app that can do X". How do you qualify if they're wasting their money?
Tell me about some logistical implications of this tech in the enterprise?
How does developing an XR app differ from a traditional 2D or 3D game / app?
Specifically, what are some downsides to translucent displays (HoloLens, Magic Leap), and how do you accommodate for them?

Angular Best Practice and Guidelines

Best Practice

Each component and template should not exceed 400 lines.
Make functions smaller. The maximum lines on a function should not exceed 10-15 lines (derived from Uncle Bob’s clean code)
Use consistent name for all assets. Make classes upper camel case. Class name should be noun and method names should be verb.
Append symbol name with conventional suffix. (for example, the login component can be named as LoginComponent with Component suffixed).
File name should have conventional suffix. For example, a component can have its name suffixed with component.
Use lower camel case for naming selectors and components.
Separate words with hyphens in selectors

How Does It Work

All you have to do, to extend your trial period, is change number in TrialKey element in application.xml. This file is located in /Applications/Adobe Illustrator CC 2018/Support Files/AMT/AI/AMT. You can navigate there with this command:

cd /Applications/Adobe\ Illustrator\ */Support\ Files/AMT/AI/AMT

Then you have to open the file and edit it. You can use just nano editor in terminal.
