Generally within the first two weeks. The variance here is usually based on familiarity and affinity for our technology stack, as well as experience level. I also try to make sure all new engineers have a team mentor available to ask questions and help them along with their tasks, code review, and first deployments. I make it clear to the mentor about my expectations around their time investment in making their new teammate successful. More than two weeks suggests the dev environment is suboptimal and requires too much tribal knowledge to get things done. It also suggests the new developer isn't being setup for success by their mentor or the tasks aren't well thought out. More than four weeks, and you have to look at the new developer and see if they are the right fit. Getting signals from their mentor is really important in gauging this.
