Kroger coding interview / online assessment, format and difficulty (took it last month)

Did the Kroger KTD online assessment in May 2026 as part of the process for a software engineer II role. Here's the format and what I actually saw.

Platform: HackerRank. Standard setup. You get the full environment, no IDE restrictions, can use any language.

Format: 2 coding problems, 90 minutes. Plus a short multiple-choice section on CS fundamentals (maybe 10 questions, 10 minutes). The multiple-choice was basic: Big-O notation, SQL joins, some OOP concepts. Nothing weird.

Difficulty of the coding problems: One was straightforward array manipulation. Classic medium-tier stuff, like tracking running totals or grouping items. Second one was trickier: involved graph traversal, BFS variant. I'd call it a solid LeetCode medium verging on hard. Not the hardest thing I've done on a loop, but you need to actually know your data structures.

I used Python and didn't feel penalized for it. Solutions just needed to pass the test cases.

Time pressure: 90 minutes for 2 problems is reasonable if you've been grinding. I finished with about 20 minutes left. If you're rusty on graphs, that second problem might eat your clock.

What they're not testing: System design isn't part of the OA. No open-ended questions. No architecture. Pure coding.

After the OA, I heard back in about five business days to schedule the next round (phone screen with an engineer). So they do move but it's not Amazon-speed.

For context, I was applying to a hybrid role in Cincinnati. No idea if difficulty varies by location or team but I'd assume similar across KTD.

If you're wondering whether to prepare: yes, standard LeetCode medium prep is the right call. Don't skip graphs, trees, and hash maps.

was the BFS problem on a standard grid or something more abstract like a dependency graph? trying to calibrate whether to focus on grid traversal or general graph problems

more abstract, not a grid. think adjacency list input. but prep both, grid BFS is easy practice and grid problems show up sometimes in screens at retail tech companies (store proximity, delivery radius stuff).

Thanks for the detail on the multiple choice section. I keep seeing conflicting info on whether Kroger's OA has that section or not. Good to know it's still there.

the CS multiple choice section is kind of a throwback. feels like a university exam. but I guess it filters out people who faked their way through their resume.
