Travis Kimmel talks with Kevin Goldsmith about the correspondence between organizational design and software architecture.

Common friends - coding exercise

Imagine we have data for users of a social network. Users can befriend other users of the network.

We want to implement a feature where a user Alice visiting another user Bob, would see which friends Alice and Bob have in common.

Write a script/function/program in your preferred programming language that takes two user names and gives back a list of the common friends between those users.

Things we currently do to set up an A/B test as an engineer

Planning

Review the tasks
- Understand what is being asked to be tracked and why
  - Analyze feasibility of implementation provide feedback and ask questions with Product and Analysts
Flesh out the technical information (see Development) of such tasks
Ensure there are separate tasks created for implementation of tracking, and
