One piece of advice. It is easy to start with an existing team, product or company and immediately find things that in your opinion are done “wrong”. One of the fastest ways to alienate yourself is to come in with a sledgehammer and start trying to change everything after only a couple of months on the job. Step back and realize there is or was likely a good reason that certain choices were made. Try to really understand the why. Maybe that will change your opinion of some of the choices. Then armed with that understanding you can suggest and make improvements in a way that brings value to the team.
