Pathfinder：把留学与面试经历整理成证据

Field notes

The archive separates study-abroad research from recruiting evidence, with filters framed around concrete decisions such as intake season, program format, role family, seniority, region, and interview stage. Visible records range from TPM and PM interviews to coding, machine-learning, and system-design prompts. Several entries preserve useful operational details—sponsorship questions, hybrid-work requirements, round timing, and candidate background—while explicitly acknowledging when an experience date is unavailable.
