Test Yourself: Real Partoo Questions
Three real prompts pulled from our database.
Type · Behavioral
At Partoo, we often balance building new features for local business visibility against technical debt incurred from scaling our review aggregation pipelines. Describe a time you had to advocate for prioritizing a refactor or infrastructure improvement over a requested customer feature. How did you quantify the impact of that technical work to non-technical stakeholders?
Type · Algorithmic
Given a list of customer reviews for a local business, write a function to identify the top 3 most frequently mentioned positive keywords and the top 3 most frequently mentioned negative keywords. Assume reviews are pre-processed into a list of words.
