A mistake I used to make: not preparing for the onsite interview. Things like... * Researching your interviewers beforehand. I start with LinkedIn. It can be useful to know if they have just joined the company, or have been there for years. * Making sure you have some good stories to tell about your most recent role, what things _you_ did/influenced/changed. Practicing them with a friend or spouse. * Being physically prepared for the interview, getting a good night's sleep beforehand, arriving at the office in plenty of time so you're not flustered. I aim for >30 minutes early. Don't actually go into the office until 5-10 minutes before the interview is scheduled to start though. * Finding out about the dress code at the company, and dressing accordingly or, if in doubt, slightly (but not too much!) smarter than the dress code you expect. * Being ready to give a good handshake - warm, dry, and politely firm. If you notice your hand is cold and clammy beforehand, sit on it for a bit! * Making sure you are polite and courteous to everyone you meet in the office. Maintain your posture. If you normally chew gum, don't. Assume that the interview starts the moment you set food inside the building. * Be ready to appear fascinated and interested in the job role. Have some smart questions to ask at the end when they say "any questions?"
