Pair Programming: Take-Home Extensions
Interview overview
●
During the interview, we will be extending your take-home project by adding new features. These features might
look like extending the UI, or modifying the data model. Each extension will have multiple parts/layers, so pace
yourself accordingly.
●
Make sure to analyze requirements upfront. Before you start coding, ask clarifying questions to better
understand the problem.
●
Our extension interviews are designed to assess your coding proficiency. We’ll want to aim to have working code
at each step of the extension. Try to discuss the technical decisions you’ve made along the way. Our goal is to
learn how you think, how you code, and how you collaborate.
●
For this interview, you will be using your personal computer and sharing your screen as we work on the project.
After the interview ends, you should submit the code to the interviewer.

Q&A Past Software Design
Interview overview
●
The purpose of this interview is to explore and understand your contributions to a technical project that best
reflects your abilities, to get a clearer sense of how you’ve applied your technical knowledge in the past.
●
We will ask you to choose a project that you’ve worked on that exemplifies your best skills. We will then discuss
your contributions to the technical direction of that project, your contributions to planning, the technical
architecture, the execution of the planning, testing, the project launch, and reflections post-launch.
●
Expect to dig deeper into some of the technical details and architecture of your project, and talk about some of
the technical decisions and tradeoffs you contributed to.
●
We recommend that you choose a project that reflects the upper limits of your abilities, and that demonstrates
the kind of scope, complexity, teamwork, scale, and impact that you wish to portray. This way, interviewers can
develop a more accurate sense of your technical abilities. The project doesn’t have to be recent, but you should
expect to answer some in-depth questions.
●
If you feel that a diagram may help you explain your work better, you're welcome to either prepare it in advance
of the interview, or draw it during the interview. (Google Docs, Google Jamboard, pen & paper, etc.)

Q&A Getting Stuff Done
Interview overview
● The purpose of this interview is to learn about your contributions to
the larger engineering team, beyond the technical architecture.
We’ll look to understand how well you’ve collaborated within your
team and with others, your role in project planning, execution, and
retrospectives.
● This interview is meant to cover your broader responsibilities as an
engineer. Expect to talk about your experiences communicating
with stakeholders, collaborating with other engineers, working as a
team, and scoping, launching, monitoring your project, and more.
● Be prepared to provide specific examples of projects and situations
you contributed to, without revealing anything that's confidential or
could be considered a trade secret. Note that it is perfectly
acceptable to use the same project as in Q&A Past Software Design,
but you can also draw answers from other projects in your career.

Q&A Technical Leadership

● Candidates with tech lead experience will have an additional Q&A
Technical Leadership interview. This interview is used to more
