🟡
We are crazy about technology, serious about people.
Może oznaczać zarówno autentyczne zaangażowanie w innowacje i dbanie o pracowników, jak i być pustym sloganem marketingowym.
🔴
from defining project requirements, to designing, building, and deploying software applications
Może sugerować szeroki zakres odpowiedzialności, który wykracza poza samo kodowanie, włączając w to analizę biznesową i zarządzanie projektem.
🔴
common codebase
Wskazuje, że praca będzie polegać na modyfikowaniu i rozwijaniu istniejącego, współdzielonego kodu, co może ograniczać swobodę w implementacji nowych rozwiązań.
🔴
~ 4 months with possibility of prolongation
Określony, krótki czas trwania projektu może oznaczać, że po jego zakończeniu umowa nie zostanie przedłużona, mimo obietnicy możliwości prolongaty.
🟡
clean architecture, reusable components
Choć brzmi profesjonalnie, może oznaczać, że oczekuje się od Ciebie utrzymania i rozwijania istniejącej, być może już skomplikowanej architektury, a nie tworzenia jej od podstaw.
