Those are insightful answers to an array of interview questions. The only quibble I have, as someone on the other side of the desk, is with the answer to "When are you able to start?". Instant availability is desirable; however, if you are currently employed I would prefer to hear that you need to give notice at your current job and may need to start at a later date. It shows that you are responsible, considerate and are not as likely to leave without notice if something better comes along.
