Tetra Tech Environmental Scientist/Engineer interview questions

This was an initial screening interview for an entry level position. The interviewer was fairly laid back. All of the questions asked were basic/expected. I was definitely unprepared for the interview questions because I did not know that he would interview me when I called him, so I didn't articulate my responses to the questions as well as I would have liked. I just interviewed with him today (May 25, 2012). He said he would get back to me in a couple of weeks.
