Hiring Scientist, FirstWho

"Hiring here is hard because you need someone who can own an entire payment module from architecture to deployment while still admitting when their initial component design was wrong. You want Clear Communication evidenced by their ability to explain complex RxJS stream logic to a junior without condescension, and Intellectual Humility shown when they volunteer that their first attempt at state management created memory leaks. They need Component Architecture & Design Systems skills to build a date-picker that survives timezone edge cases across three product areas, plus Performance Engineering & Optimization chops to prove they reduced bundle size by forty percent through lazy loading, not just talk about it. Most candidates have one or the other. Finding both is rare."

Competency Questions

1 of 18

Component Architecture & Design Systems

Designs smart/container components and feature modules; creates custom directives and pipes; establishes component patterns within squad-level repositories.

Why this level

Essential for daily feature delivery within module ownership scope; manifestation explicitly defines mid-level responsibilities for establishing reusable patterns and smart/container component separation.

Risk if missing

Inconsistent component patterns lead to technical debt accumulation, reduced code reusability across features, and increased cognitive load for code reviews; poor container/presentational separation results in unmaintainable state logic scattered through templates, making testing and refactoring prohibitively expensive.

Walk me through how you built a component that other teams ended up adopting.

Select Interview Round

Assuming 5 minutes per question response

Positive Indicators

  • Mentions specific API design decisions
  • Discusses trade-offs between generic vs specific solutions
  • References design tokens or visual consistency

Negative Indicators

  • Focuses only on visual implementation without reusability

  • No mention of documentation or contracts
  • 🚩No consideration of backward compatibility
  • 🚩Dismisses design system standards

Attitude Questions

1 of 22

Clear Communication

The ability to translate complex technical concepts, constraints, and architectural decisions—specific to Angular frontend ecosystems—into precise, audience-appropriate language that enables informed decision-making across technical and non-technical stakeholders. This includes structuring information hierarchically, distinguishing between certainties and uncertainties, quantifying business impact, and bridging knowledge gaps between engineering disciplines without oversimplification or condescension.

Give me an example of how you explained a technical constraint to non-technical stakeholders when it affected their delivery expectations.

Assuming 5 minutes per question response

Positive Indicators

  • Uses concrete analogies related to stakeholder's domain
  • Focuses on user or business impact
  • Offers alternative timelines or scopes
  • Checks for understanding explicitly

Negative Indicators

  • Relies heavily on technical jargon
  • Blames stakeholders for 'not understanding code'
  • Presents binary options without nuance
  • Avoids the conversation entirely
  • 🚩States that non-technical people should just 'trust engineers'
  • 🚩Demonstrates contempt for explaining technical work
  • 🚩Admits to hiding constraints until delivery failure
