Q: Is there a relationship between interviewing well and being a good lawyer?
A: In many cases yes. If you can think quickly and artfully tailor your response to a question, delivering information confidently, clearly, and cogently, you have skills needed for interviewing and practicing.
However, in practice you also need to be efficient with your time and collaborative as well as competitive. Some great interviewees turn out not to be team players or have the work ethic it takes to excel in a service role. So while there is a relationship between interviewing and practicing law, the differences are what makes it hard to be right 100% of the time in hiring.
