Requirements and Qualifications
Previous experience in search engine evaluation is required, including work assessing search relevance, query corrections, or product categorization. Strong written and spoken English is also required so you can accurately interpret queries and explain your decisions.
You should be comfortable analyzing nuanced differences between product categories and attributes, navigating search engines, and following strict annotation protocols.
