Attention to Detail and Quality Questions

Covers the candidate's ability to perform careful, accurate, and consistent work while ensuring high quality outcomes and reliable completion of tasks. Includes detecting and correcting typographical errors, inconsistent terminology, mismatched cross references, and conflicting provisions; maintaining precise records and timestamps; preserving chain of custody in forensics; and preventing small errors that can cause large downstream consequences. Encompasses personal systems and team practices for quality control such as checklists, peer review, audits, standardized documentation, and automated or manual validation steps. Also covers follow through and reliability: tracking multiple deadlines and deliverables, ensuring commitments are completed thoroughly, escalating unresolved issues, and verifying that fixes and process changes are implemented. Interviewers assess concrete examples where attention to detail prevented problems, methods used to maintain accuracy under pressure, how the candidate balances speed with precision, and how they build processes that sustain consistent quality over time.

Write a Python function detect_trailing_whitespace(path) that scans a given file path or directory and returns a list of files and line numbers containing trailing spaces or tab characters. Explain how your implementation handles binary files, very large files, different encodings, and how you would integrate this check into a pre-commit hook or CI pipeline.
