How long does it usually take to adapt and start active work on a new project?

The adaptation and start of active work in a new project depend on several factors: project complexity, developer experience, quality of documentation, and team support.

For a junior developer, it usually takes from 2 to 4 weeks to understand the architecture, master the codebase, and start making changes with minimal supervision.

For a middle developer, this period can be 1-2 weeks, as they already have experience with quick immersion and understanding new technologies.

It is important to consider that active work is not only writing code but also understanding business logic, development processes, and team interaction.

Example: if the project uses a familiar stack (e.g., Python and Django), adaptation will be faster than if it requires learning new frameworks or complex domain areas.
