PM даёт задачу с нереальным estimate — что делать?

If a PM gives an unrealistic estimate, it is important to discuss this with them immediately, explaining the reasons why the estimate seems unrealistic. Provide a justification based on experience and technical details of the task. You can suggest breaking down the task into smaller sub-tasks with separate estimates to improve accuracy. If deadlines are critical, discuss priorities and possible compromises on functionality or quality. The main goal is to maintain an open dialogue and collaboratively find realistic solutions.
