• Direct Roadmap Influence: Forget the bureaucracy of big defense. You will have a seat at the table, directly shaping our product and technology trajectory from day one.

9 Mothers Policy on the Use of Artificial Intelligence (AI) During the Interview Process

The interviewing process is a mutual opportunity for us to get to know each other better. Our goal is to understand your unique background, evaluate your problem-solving abilities, and ensure a strong mutual fit.

AI is a core part of how we work at 9 Mothers—we actively encourage and frequently leverage AI tools in our day-to-day operations. However, during the hiring process, we need to evaluate your fundamental skills and expertise, not the outputs of an AI model.

To ensure a fair and transparent process, we ask that you adhere to the following interview guidelines:

• 1st-Round Interviews (No AI Allowed): The use of AI tools, assistants, code generation tools, or real-time copilots is strictly prohibited during all first-round interviews and assessments. The use of AI during this stage will result in immediate disqualification from the hiring process.
• 2nd-Round Interviews (Guided AI Usage): The second-round process includes opportunities to utilize AI. Your interview team will provide explicit guidance on how, when, and which AI tools to leverage during this stage.

We appreciate your cooperation in helping us maintain an authentic and fair interview experience for everyone.
