I am a new grad. Did a few internships in the past, but don't have any other experience. Are there any common pitfalls or mistakes Nooglers make or tips you can give for starting my 1st month (maybe year) at Google, or any SWE job? Any preparation I can do in advance like learning a particular framework or how "X" works? Should I introduce myself to every team member on the first day? Is adding team members on Facebook a good idea, bad, or not matter? Etc. Thanks!
Ask google first, then verify with more experienced co-workers.. the thing is you need to know how to find the answer. You will never be able to have all the answers.
Don’t add work people on Facebook!!! Bad idea. Unless you become de facto friends.
Ask lots of questions but try to batch them in 15 to 30 minute sessions. Batching questions will make you reflect on what to ask and will be respectful on your coworkers time.
