Additional Details:
Quick team layout line. This is a backend team that uses Javascript, typescript m and nodejs to build reusable libraries not just UI components. You need to write JS test frameworks to test with. Need to be heavy in JS, React is a nice to have at this point its more to support the consumer of the library
Some additional things from previous feedback from candidates

1. Coding people have being passing mid, need too really excel here.
2. People have been falling short on operational excellence, ability to triage production issues, rootcause, and measure the outcome

4. Need to be able to do work like sequence diagram, state machine

1. They will take you through a paired programming session. Please be sure to be able to describe your methodologies as you right them, and be prepared to give more than one solution to a problem
2. They will be having a conversation with you and expect a bit of back and forth in terms of banter on ideas and curiosity. Some example questions are below. Please make sure to ask questions about the questions they are asking so you understand what they are looking for
Design:
* Help me run down with your experience.
* Give me some details about your current team.
* How do you get confidence in code?
* What happens when build passes?
* What is your primary expertise?
* Is there a project you are proud of?
3. They like candidates who can focus in on a topic of discussion, rather than someone who says a bunch of technologies. More focused. We had a candidate get declined for taking a lot of time on Intro
4. As stated above, don't go through the life story. Focus on 1-2 areas that are relatable vs a basic overview of 30 things.
