What is the following in red saying?
Theresa was relatively new to project management, after nearly a decade in product development. She knew Riva's software family inside out and enjoyed the cutting-edge innovation, technical challenges, and innate elegance of the company's products.
Does this mean "she knew Riva's software family very well and deeply"?
Thank you.
Yes - she knew every last tiny thing that could be known.
Context is always important; labelling is rarely important.
