How long does it usually take to integrate a new team member into a project?

The time to integrate a new team member into a project depends on several factors: the complexity of the project, the developer's experience, and the quality of documentation.

Typically, for a junior developer, it takes from 2 to 4 weeks, including familiarization with the codebase, tools, and development processes.

For a mid-level developer, integration may take 1-2 weeks, as they already have experience and an understanding of general principles.

It is important to provide the newcomer with access to documentation, a mentor, and simple tasks for gradual immersion into the project.
