That got me right back on track, and I made a quick mental note to focus on the design. Another important thing to remember is to not blabber away, but try to have more of a conversation in this part. The recruiter will always have questions, so try not to go on with a saga, but leave room for questions in between. A free flowing conversation will leave more room for you to correct yourself, come back on track, and get cues as to what the recruiter is expecting to hear.
