Simplifying Interview Prep

Simplifying Interview Prep

To help how comfortable users felt during practice sessions, I designed a split screen structured interview layout that displayed the mock interviewer's feedback and live transcript, as well as the integrated development environment (IDE) on the left for them to jot down their ideas.

I also built an atomic design system to improve developer collaboration, helping the team reduce wireframe build by 50%.

Background

Interview Anxiety & Lack of Confidence

Breaking into tech is tough, especially for underrepresented candidates facing structural barriers. The numbers speak for themselves, as candidates often experience:

🔹Interviews with 7 companies on average

🔹4-7 rounds interviewing, per company

🔹Navigating the job search for an average of 6 months before receiving an offer

Therefore, candidates could experience upwards of 50 interviews for different companies over their job search process. For many, the process is exhausting. A performance poorly in an interview can impact earnings for years, disproportionately affecting candidates who identify as Women, Black, Latinx, Native, Pacific Islander, and LGBTQ+.

Findings

Preparing for High-Stakes Interviews Without a Clear Path

By conducting semi-structured user interviews with participants in undergraduate and masters programs, as well as jobseekers hoping to pivot into tech, I uncovered key obstacles they faced, such as:

🔹Ongoing stress & self-doubt from lacking a structured approach and curriculum to follow, especially for roles assessing both technical and behavioral skills

🔹Inability to take advantage of the tool's full capabilities because of undiscoverable core features, such as creating custom questions and progress tracking


Motivated Users, Unusable UX

Additionally, I conducted usability tests with participants. These helped me observe user interactions and motivations, and identify screaming usability issues:

🔹79% of users expressed interest in reusing this tool for future interview preparation

🔹However 63% of users felt dissatisfied with the tool's usability, pointing to low re-engagement rates

My Approach

Sustainable Prep for the Long Haul

As the founding designer and researcher, I designed the MVP from zero-to-one, implementing a new intake form that caters to users diverse interests and career goals, a gamified dashboard to increase user-re engagement, an interview practice tool with a split screen paneling, and session completion pages.

What was the impact?

Driving Growth & Revenue

The startup brought me in to revamp their UX/UI as they continued hosting sales calls and presenting at pitch competitions. Post-launch, the tool saw strong user traction and revenue growth, and my designs played a pivotal role in helping the startup land its first enterprise client.

Another key metric directly reflected a pain point candidates raised during initial user interviews: many users wanted the ability to explore multiple careers and prepare for more than one role. In response, the platform introduced flexible, role-based dashboards that allowed users to switch between career paths. As a result, just two months after implementation, the platform saw a 47% diversification in the roles users were preparing for.
