2.1 Stage 1: Application & Resume Review

The process begins with a thorough review of your application materials, focusing on your experience as a Product Manager—particularly with B2C or B2B API products, your ability to work cross-functionally, and your track record of shipping impactful projects. Demonstrating strong written communication and ownership in your resume is key. Tailor your application to highlight collaboration with engineering, GTM, and design teams, as well as any experience launching new products or running pilots with customers.

2.2 Stage 2: Recruiter Screen

Next, you’ll have an introductory call, often with a founder or senior team member. This conversation is designed to explore your motivation for joining Column Tax, your problem-solving interests, and your alignment with the company’s mission of building transparent, user-centric tax products. Preparation should focus on articulating your career narrative, your approach to ambiguity and change, and your enthusiasm for working in a dynamic, collaborative environment.

2.3 Stage 3: Technical/Case/Skills Round

This stage assesses your product thinking, analytical skills, and communication abilities. You may be asked to complete a written product scenario exercise or submit a writing sample that demonstrates your ability to distill complex concepts for technical and non-technical audiences. Expect scenarios that test your approach to metrics (such as evaluating promotions or business health), stakeholder communication, and prioritization of deadlines. Prepare by practicing concise, structured responses to product challenges and showcasing how you approach data-driven decision-making.

2.4 Stage 4: Behavioral Interview

A founder or senior leader will conduct a deep dive into your resume, focusing on your professional journey, transitions between roles, and major projects you’ve shipped.
