Wildberries Marketplace interview questions

The interview process at WB consisted of several stages: 4 interview rounds in total, plus a take-home test assignment. The first stages were more general and focused on my previous experience, motivation, relevant projects, and basic understanding of the business analyst role. There was also a test assignment, which assessed my ability to structure a problem, work with data and logic, and formulate clear conclusions. The last two rounds were the most substantial and each lasted around one hour. They were conducted with the Strategy Team Lead and a Senior Manager. The main focus was on testing hard skills and logical thinking. I was asked many logic-based and market-sizing questions, mostly in the guesstimate / Fermi problem format, for example: “How many yellow cars are there in Czechia?” For these questions, the exact final number was less important than the reasoning process. The interviewers wanted to see how I structured ambiguous problems, what assumptions I made, how I broke the task down into smaller parts, and how I checked whether the final estimate made sense. Overall, the process was quite intensive, especially during the final stages. It is important to be ready to think out loud, quickly structure unclear problems, and confidently explain the logic behind your answer.
