About Clerkie

By pairing the two through the Clerkie network, these tools have become the go-to resource for creditors looking to manage loan losses while simultaneously helping millions of borrowers get out of debt.

Clerkie is a remote-first company, with over 40 employees spanning 4 time zones across the United States. To date, the company has raised $41 million, including a $33 million Series A round in early 2023.

Our Process

Our hiring process is intentionally designed for you to interview Clerkie as much as our team is interviewing you. We've built a 5-step process that allows for a two-way assessment across skills, behaviors, values, technical ability, ways of working, and adaptability in a lean startup environment.

  • Application & Coderbyte (async candidate time)
  • Intro Screen w/ People team (20-30 minutes via Google meet)
  • Take-Home Challenge & Live Review w/ Sr. Engineer (challenge is async candidate time, live review is 45 mins via Google meet)
  • Live Coding Challenge w/ another Sr. Engineer (90 minutes via Google meet)

We approach this stage with transparency and sensitivity, and candidates will be provided with clear information about the process.
AI & Interview Assessments

At Clerkie, we embrace AI and use it throughout our day-to-day work. We value people who thoughtfully leverage modern tools to learn, build, and solve problems more effectively.

Our interview process is designed to evaluate each candidate's own technical thinking, communication, and problem-solving approach. To help ensure every candidate is assessed fairly, consistently, and under the same conditions, we ask candidates not to use external problem-solving resources during live interviews or technical assessments unless we explicitly state otherwise. This includes AI assistants, interview assistants, search engines, and other third-party resources. You're welcome to reference any documentation or materials that we provide as part of the interview.

This expectation does not apply to approved interview accommodations or assistive technologies. If you require a reasonable accommodation at any stage of our hiring process, please let us know. We're committed to providing an accessible and equitable interview experience for all candidates.

If this interview expectation is not followed, we may conclude the assessment and discontinue the interview process.
