Science Question:

They will be looking for why you chose your project, how you undertook it, what you got out of it and what you enjoyed about it. They might ask you to justify the results. Make sure that you have read through your project before the interview to refresh you memory.

If it was a team based project they will be interested in how you fitted into the team, what role you took in the team, how you co-operated with the other members - especially when there were problems.

If the project was an individual project you can talk about the discipline of having to work independently with little supervision, having to find things out for yourself, how you went about solving problems.

If you used any scientific techniques that you are likely to be using in the job you are applying for, then put particular emphasis on these.
