When interviewees get these questions, the tendency is to over think them. It is true that the interviewer is trying to dig deeper into your experience and your character, but do not over complicate your answer to the point where you really aren't saying anything meaningful. For the question, tell me something about yourself, remember, they have already seen your resume, so don't spend time rehashing that information. Think about it ahead of time and identify something that is not on your resume, but that speaks to your character or your general ability to do the job well. Also, try not to get into too many personal details here, such as 'I have X number of children', etc., but do see if you can find a personal connection to the interviewer. If you see something in their office or heard something in what they told you about themselves, try to find a common ground such as going to the same school or rooting for the same sports teams, etc.
As for the question, what are your weaknesses, this is tricky. You have to show that you are humble and honest about yourself, but at the same time are strong and reflective. In other words, you know how to identify your mistakes and quickly learn and grow from them. For example, you can say something like you identified what you thought was a great process improvement and you pushed hard to get it changed ASAP, but you quickly realized that fast and forced change is not received well in your work culture. You then, took a step back and developed a more formal change management plan.
