2.1 Stage 1: Application & Resume Review

The process begins with a detailed review of your resume and application by the product and recruiting teams. They look for evidence of product ownership throughout the lifecycle, experience launching consumer-facing products, and a strong foundation in analytics and metric-driven decision-making. Highlight your experience in agile environments, collaboration with engineering and design, and any background in health tech, data-driven product decisions, or AI/ML-enabled features. Tailoring your resume to reflect leadership in ambiguous, fast-paced settings and clear communication of product vision will help you stand out.

2.2 Stage 2: Recruiter Screen

A recruiter will reach out for an initial phone or video conversation, typically lasting 30 minutes. This screen assesses your motivation for joining January AI, your alignment with their mission of personalized health insights, and your general fit for a startup culture. Be prepared to discuss your product management background, why you’re interested in precision health, and your ability to drive results in a metrics-focused environment. Reviewing January AI’s recent coverage and having a point of view on their product vision is recommended.

Expect to tackle product case studies and technical scenarios relevant to consumer health, user journey analysis, metric selection, feature prioritization, and growth initiatives. You may be asked to analyze user data, design dashboards for personalized insights, propose experiments for retention or engagement, and articulate tradeoffs between user experience and technical constraints. Preparation should focus on structuring your approach to ambiguous product problems, demonstrating analytical rigor, and showcasing your ability to collaborate with technical teams.

2.4 Stage 4: Behavioral Interview

Behavioral interviews are conducted by hiring managers, product directors, or cross-functional peers. These sessions probe your leadership style, communication skills, organizational abilities, and how you handle ambiguity and competing priorities.

Highlight examples where you’ve driven product excellence, made data-informed decisions, and adapted quickly to changing requirements.

2.5 Stage 5: Final/Onsite Round

The final round typically consists of a series of interviews—often 3-5 sessions—with senior leadership, engineering, analytics, and design stakeholders. This stage may include a product presentation, deep-dive case exercises, and collaborative problem-solving scenarios. You’ll be evaluated on your ability to articulate product vision, roadmap strategy, and communicate complex ideas to both technical and non-technical audiences. Demonstrating your understanding of health tech, user-centric design, and agile product development is key. The onsite rounds also assess cultural fit, alignment with January AI’s mission, and your ability to thrive in a dynamic, inclusive startup environment.

2.6 Stage 6: Offer & Negotiation
