D4 Construction Services interview questions

I interviewed once with one owner, then again in a group interview. Owners and other employees seemed very nice and caring during the interview process. Clearly a small company, they work out of a building that looks like a house. They are so small they have no janitor service. During the interviews, the employees were very quiet and continued working at their desks. They did not acknowledge me unless they passed me, but all who did speak to me were very polite.
