What does NOT constitute the practice of law?

Interviewing witnesses unless under oath is often viewed as a preliminary investigative function rather than an act that constitutes the practice of law. The practice of law typically involves applying legal principles, representing clients in legal matters, and appearing in court. Conducting depositions, preparing legal briefs, and drafting legal documents all require a legal understanding and are integral components of providing legal services and advice to clients.

In contrast, interviewing witnesses can be a part of fact-finding and gathering information that may later be used in legal proceedings but doesn't involve the exercise of legal judgment or advocacy. Therefore, this activity does not meet the common definitions of practicing law, which normally encompass activities where a legal professional must understand and apply the law in concrete situations.
