There's so much good stuff here, I'm taking notes myself. One thing I'd like to add to bunch is this: When interviewing for a position, always be kind and friendly to the receptionist when you check in. The receptionist is like the secret spy of any organization and let me tell you I've seen many very good candidates railroaded in the hiring decision process because word got back to the hiring manager that the person was very rude to the receptionist or reception team. "Rude" can mean all kinds of things. It could mean that you weren't cordial, or you were entitled, snotty, brash, disrespectful, you name it. I also once had a receptionist tip me off to the fact that the candidate had fallen asleep in the lobby. It's not super often that someone being overly nice can get them the job, but it can most definitely work against you. Nothing screams "not a culture fit" like someone who doesn't bother to turn on the charm for the very first person they encounter for an in person interview.
