GL in your interview and really good stuff from the comments. Just be comfortable and dont feel like you need to be perfect. Lighten up and sound confident. And as for weaknesses, say something that you might not have been good with in the past and tell them how you've learned from that. For example, if you used to work in groups your weakness couldve have been being too controlling and wanting to do most of the work so nobody else would mess it up. But you learned that you might need to take a step back and work as a team so you can accomplish the job as a team and not just by one person. GL
