Ask HN: What best practices you use to onboard yourself in a new company?
This could vary based on your experience , background, domain. Would be great to include some context on why something worked or did not.
One thing I did when I started my current job, was drawing out a floorplan with the names of people at their desk position, their project (and role if known). Sure it was far from complete on day 1 but it helps me learn and remember the names of everyone.
Outlook also has another handy feature: when you click on someone it shows people that that person frequently talks to. Consider figuring out who your team / manager talks to and what those peoples roles are.
Take note of a person's title / role and consider the roles of people reporting to someone and their role.
