🔴
Contributing to architectural and product decisions
Może oznaczać faktyczny wpływ na architekturę i produkt, ale równie dobrze może być pustym frazesem bez realnej możliwości decyzyjności.
🔴
6+ years of experience
Wymaganie tak długiego doświadczenia w Pythonie może sugerować, że szukają kogoś na stanowisko seniorskie, ale równie dobrze może być przesadzone w stosunku do faktycznych potrzeb projektu.
🔴
4+ years, fullstack frontend development
Długie doświadczenie w frontendzie z Next.js może sugerować, że oczekują eksperta, który będzie samodzielnie budował złożone interfejsy, a nie tylko wspierał backend.
🔴
2+ years, practical experience integrating AI models
Wymaganie doświadczenia z LLM może być przesadzone, jeśli projekt zakłada jedynie proste integracje, a nie zaawansowane prace z modelami.
🔴
5+ years, including NumPy and analytical workflows
Tak długie doświadczenie w Data Science może sugerować, że rola będzie bardziej analityczna niż typowo developerska, lub że oczekują kogoś z szerokim zakresem umiejętności.
