JavaScript Engineering Interview Questions

What kind of work are you excited about?
Tell me about a project/deployment/failure that went majorly wrong and how did you or the team recover and what did you learn from the situation?
How do you go about testing web application functionality and components?
Do you have working familiarity with any of the major web application frameworks? Can you describe some examples of projects that have used these frameworks?
- Angular, Ember, React, Backbone?

What were the greatest challenges you've faced in working on those applications/projects?
