We know pursuing a new career opportunity can be daunting.

Whether through the conversations with technical team members or with leadership, we want you to walk away feeling seen, heard, and given every opportunity to succeed.

The Technical Coding Challenge

This brief assessment aims to evaluate technical skill and proficiency. We understand that technical assessments can be overwhelming; we aim to make our challenge clear with realistic requirements. We ask candidates to spend no more than an hour on this challenge, and submit the assignment within 36 hours of receipt. This stage is intended to assess your technical ability in the following areas:

  • Completeness and correctness (adherence to the specifications)
  • Tests that describe the requirements and protect against regressions
  • The design and structure of your code
  • Code that is well documented and works as described

We encourage you to choose the language and tools you feel most comfortable with.

There is also a short-answer question to gather your thoughts on scalability. You may pick one of three questions to answer. This should take no more than a few short paragraphs to answer, and you should reserve time within your one-hour window to answer it.

Pair Programming Interview

The 90-minute Zoom Pair Programming Interview includes two collaborative 8th Light senior or principal developers/crafters). This session is "bring your own environment." Come prepared to code in your editor or IDE of choice, sharing your screen via Zoom, and we'll work along with you to develop code and tests to solve the problem presented.

There will be two segments of this interview.

  • Pair Programming (approximately 55 minutes): Candidates will work on a command-line app, driven by unit tests.
    • Language Choices*: JavaScript/TypeScript, Ruby, Python, Java, Elixir, C#, Scala, Clojure, Swift or Kotlin
    • Goal: Complete the exercise, while incorporating test-driven design (TDD) practices and working collaboratively with the interviewers.
  • Code Review (approximately 25 minutes): You’ll review code of a small web-based application, providing feedback and commentary along the way to the team.
    • Language Choices*: Ruby, Python, or TypeScript
    • Goal: Explain issues to the junior and to identify aspects that prevent the code from being production ready or overly buggy.

*Candidates must choose two different languages for these two segments (e.g., if you select Ruby for the first segment you cannot use Ruby for the second). This allows us to evaluate a candidate’s comfort working across multiple languages.

Candidates will be allotted time to ask questions to the interview team.

Architecture & System Design Interview

In the 90-minute Zoom Architecture & System Design Interview, you’ll role-play with two experienced 8th Light developers/crafters in a hypothetical client conversation.

As consultants, clients often look to us for answers on how their systems should be built. Sometimes we make decisions unilaterally, sometimes we need to convince clients, and sometimes we need to work within their constraints.

Goal: Demonstrate ability to be adaptable and to apply concepts and knowledge base to help a hypothetical client identify the right approach. Expect to discuss the following:

  • Technology choices and trade-offs
  • Distributed Systems
  • Security
  • Scalability
  • Maintainability

The Consulting & Culture Interview

During the final 60-minute Zoom consulting interview, we would like to understand how you approach managing clients and team dynamics. A team of two senior leaders from 8th Light will focus on your project management ability and interpersonal skills to observe how you manage working with clients and teammates. We will be specifically interested in how you collaborate, include, mentor, and extend empathy to the people with whom you work.

Offer Stage

Once a candidate has successfully completed each stage of the interview process, the team gathers to discuss each stage carefully. As an employee-owned organization, our team’s perspective is critical to how we grow. Once there is agreement, an offer will then be made. We will do our best to provide as much verbal feedback as possible.

Offer Presentation

The Talent Acquisition Team will contact the candidate to share offer details, seek feedback on the process, and share initial developmental opportunities for a successful career at 8th Light. Prior to accepting an offer, we invite and encourage candidates to meet with our HR Manager to discuss employee benefits and perks. In addition, we can arrange coffee chats with our team to help candidates gain additional insight before making a decision.

Did not receive an offer?

Although this is not the news most plan for or expect, we hope that your relationship with 8th Light does not stop here. We invite all candidates to reach out to our recruitment team for feedback on ways to progress toward a stronger candidacy in the future.
