Often considered the "CEO" of their product area, product managers oversee the strategy, production, and implementation of a particular product. Because product management teams include members from different backgrounds such as engineering, design, and data design, product managers must have strong communication skills and excel in cross-functional work environments. Expect to answer questions about your management abilities, prioritization skills, and experience working in product. Though not required, technical backgrounds are advantageous particularly when applying for roles at tech companies.
The manager of component 'A' says his functionality is more important than that of component 'B.' The manager of component 'B' says his is more important than that of component 'A.' You can only implement one A or B, but not both - which do you choose to implement.
I reference the Product Plan and select the component w/ the higher priority. The interview says "There is no Product Plan." I say "I select the one w/ the higher ROI." They say "there is no ROI." I say "then I choose the component whose manager has the best rationale."
I would say to do my own research
