Avoid talking about what YOU want. Talk about your past projects that may be similar to the project you're interviewing for. Always be positive, and don't worry about blowing your own horn. Deadlines are common in this line of work. Use one or two examples to illustrate.
Deadlines are very important to technical hiring managers.
This is an ideal place to restate things you've said in your resume, and also to elaborate on them, using action words. As long as I think I'm making a meaningful contribution and growing my skills and responsibilities. This is a very common question. Never cite personal characteristics as weaknesses. Ideally you will find something that could be seen both as positive and negative.
