Two candidates who interviewed for Best Buy's Software Engineer role describe a similar shape: a behavioral conversation first, then a technical round. Neither received an offer, so the reports show where candidates were tested but not what a winning answer looks like.
One candidate's phone screen centered on teamwork and collaboration style. The other had a Zoom behavioral round with standard strengths and weaknesses questions, plus the toughest task in their current role, how they juggle multiple tasks, and how they would explain a complex concept to someone with no background. That candidate said they should have given more specific examples and did not advance to the technical round.
The technical round, reported by the other candidate, was online. It covered some conceptual questions, then the main task: implementing a binary tree search using recursion, coding it live and explaining the approach. Difficulty reportedly rose as the session went on. Practicing recursive traversal and talking through your reasoning while you code is the most direct preparation.
A senior-level candidate described three rounds: a manager-led behavioral session of about 45 minutes, a 75-minute coding and refactoring discussion, and an HR conversation on culture fit and career direction. Questions covered staying current with technology, making sure teammates feel heard, and the reasoning behind refactoring and technical debt. That report is one person's senior-track experience, so treat it as a hint for senior applicants only.
For most applicants, prepare two or three specific stories on prioritization, collaboration and plain-language explanation, and practice tree problems until the recursion is easy to narrate.

Real interview reports from people who went through the Best Buy process.
I interviewed at Best Buy for a Senior Software Engineer role, and the process was split across three rounds, each with a distinct focus. The first round was a manager-focused behavioral session that lasted about 45 minutes. They asked scenario-based questions, including how I keep myself up to date with technology and how I ensure team members feel heard in discussions. It was conversational and probing — less about technical chops and more about leadership style and adaptability. The interviewer seemed interested in understanding how I handle real-world management situations rather than textbook answers.
The second round was the heavier technical component, running 75 minutes. This was a full coding session where they dug into problem-solving ability and hands-on implementation skills. They asked me to walk through how I'd refactor an existing codebase — not just surface-level cleanup, but the reasoning behind architectural decisions, handling technical debt, and thinking through complexity tradeoffs. It felt less like a LeetCode grind and more like evaluating whether I could actually own a codebase and improve it thoughtfully.
Finally, there was an HR round focused on cultural fit, communication, and career trajectory. They wanted to hear about past projects, challenges I'd faced, and how I approach problem-solving as part of a team. The entire process tested whether I could balance individual technical execution with people leadership — a blend that felt specific to the senior level role. The interviews were straightforward and professional, though there wasn't much wiggle room if you stumbled on the behavioral or architectural reasoning parts.
Prep tip from this candidate
Focus heavily on behavioral scenarios tied to team leadership and refactoring decisions — they want to see your reasoning on why you'd restructure code, not just that you can write it. Be concrete about how you've handled situations where team members disagreed or had different opinions, as that question came up repeatedly.

Synthesized from candidate reports. Individual experiences may vary.
One candidate applied through a recruitment agency and got a first call about ten days later, with a recruiter guiding them through each stage. Timing and contact will likely vary by route, so confirm next steps with your recruiter after each conversation.
Candidates report a behavioral first round by phone or Zoom. Topics included team collaboration style, strengths and weaknesses, the toughest recent task, juggling multiple tasks, and explaining a complex concept to a non-expert. One candidate felt their examples lacked specifics, so prepare concrete stories.
One candidate who reached this stage describes an online technical round with some conceptual questions and then a recursive binary tree search to implement and explain. Questions reportedly became harder as the session continued. Another candidate was told a technical round would follow but did not advance to it.
A single senior software engineer candidate reports three rounds: a roughly 45-minute manager behavioral session, a 75-minute coding and refactoring discussion, and an HR round on culture fit and career path. Senior applicants may see more leadership and architecture questions, but this is one report.
