Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time marketing asked for something that would hurt site performance. How did you handle it?
What they are checking: Whether they can push back with data and offer alternatives while still serving the business goal.
Tell me about a time you mentored another developer or raised the standard of a team's code.
What they are checking: Whether they act at a senior level by improving the team, not just shipping their own work.
What front-end trend or tool have you adopted recently, and why was it worth it?
What they are checking: Whether they stay current with judgment, adopting tools for real benefit rather than novelty.
What would you do
A product launch page breaks in Safari an hour before a big drop. What do you do?
What they are checking: Whether they can triage calmly under launch pressure, fix or roll back, and communicate clearly to stakeholders.
How do you handle a design that looks great on desktop but doesn't translate to mobile?
What they are checking: Whether they collaborate with designers early on responsive behavior instead of quietly improvising.
About the work
Walk me through how you'd build a product detail page for a running shoe that loads fast on a phone.
What they are checking: Whether they think about image handling, lazy loading and Core Web Vitals, which drive both conversion and search ranking.
How do you take a design from the design team and turn it into components other developers can reuse?
What they are checking: Whether they build maintainable component systems instead of one-off pages that drift from the brand over time.
How do you make sure an eCommerce UI is accessible?
What they are checking: Whether they know WCAG basics like keyboard navigation, contrast and screen reader support, which also carry legal risk.
What eCommerce platforms have you worked on, and how did the platform shape how you wrote front-end code?
What they are checking: Whether they understand the constraints of commerce platforms like Salesforce Commerce Cloud and work within them well.
How do you test your UI work before it goes live?
What they are checking: Whether they use automated tests, cross-browser checks and code review rather than relying on manual clicking.
How would you measure whether a UI change actually improved the customer experience?
What they are checking: Whether they connect front-end work to outcomes like conversion and bounce rate through testing and analytics.
