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.

In retrospect i should have gone into more specific detail.
