I reached out to a recruiter and quickly moved into a phone screen. The technical screen was with an engineering manager, and the conversation felt strong because they didn’t just interview me—they answered my questions too and helped me understand the company.

After that, I was invited to a virtual onsite where I spoke with multiple members of the team. The interviews tested a mix of web development, algorithmic thinking, system design, and alignment with Upstart’s core values. The tone across the loop was welcoming: people were friendly, accommodating, and seemed determined to make the experience comfortable rather than intimidating.
