They don’t want the entire list. Pick some examples based on the following criteria:
How recently have you worked on it? (Don’t talk about a project that happened years ago)
Has it been successful? (Don’t talk about the one in which failed. For obvious reasons, it doesn’t help)
Is it relevant to the job you are applying for?
The whole point of this question is to test your approach and your work ethic. So, make sure that answer reflects those. Most people get carried away by this question and rattle off a lot of details. Please be concise and give only relevant details.
