Firstly make sure you are fluent with all the terminologies used in your team associated with the product line you are working on. These are nothing but the key characteristics of the product. Know how they are tested and what and what not affects them. Be fluent with the datasheet of one such product. Actively attend reviews to understand the fine line between a “good data” and “correct data”. Ask and learn a lot, showcase that you can work with the team well.
