Your first 90 days are crucial and can define your overall experience in your next position as an engineer. Preparation is the key to success in your first 90 days. Step number 1 is to connect with your teammates before you start, and LinkedIn is great for that. My suggestion is to send them the request for connecting and express the excitement of working with them. You shouldn't feel bad if they don't respond as well. They might not be as active on LinkedIn, and that's perfectly fine. I recommend doing this one week before you start, not earlier. Step 2: Start building relationships. Once you start, this should be one of your main focus points. It's important to focus on building good relationships with your team and the people that you are directly working with. You want to ensure to create a great foundation. Step 3: In your first few weeks, focus on understanding the processes, the codebase, the project, and the business as deeply as possible.
