did a virtual onsite for Home Depot's mobile/frontend platform team back in march 2026. 'onsite' is a bit of a misnomer since it was fully virtual, but the final round loop. writing this up because i had a hard time finding anything recent.
the full day was 4.5 hours spread across 4 sessions with a break in the middle. they sent a schedule ahead of time, which i appreciated.
session 1: coding (60 min) one algorithm problem, medium difficulty. i got something involving trees. they're using a custom platform (not leetcode) but it's basically the same flow. interviewer engaged with me throughout, not just watching.
session 2: system design (60 min) for my role it was mobile-flavored: design an offline-capable feature for the Home Depot app (think: shopping list that syncs when you get back to wifi inside a store, which apparently has spotty coverage). this was a great prompt. sync conflicts, local storage decisions, background sync architecture. much more interesting than abstract API design.
session 3: behavioral (60 min, two interviewers) this was the most thorough behavioral round in the loop. questions about leadership, conflict, scope of impact, working across teams. they both asked follow-ups. didn't feel like going through a checklist, felt more like a real conversation by the end.
session 4: hiring manager wrap-up (45 min) mostly Q&A and team fit. they explained the team structure and what the first 90 days would look like. i got to ask about technical roadmap, which they were surprisingly open about.
what surprised me: the interviewers were all clearly briefed on me. they'd read my resume. one referenced a specific project from my background. debrief happened fast. i heard back with a decision within 4 business days. the mobile design prompt being specific to their actual product context. it made the conversation feel real.
overall: well-organized loop. not the most grueling final round i've done but substantive.
