Feature Creep Technology interview questions

I have applied to this position from a post on a job board (Indeed.com). After about two weeks time, I have received an email from the CTO with details regarding my application, the type of company it is, and a few examples of the kind of sites they own. After reviewing the company in more detail, I have expressed my interest and was invited to an in-person interview with the CTO and the product manager. The interview process consisted of a 15 minute technical quiz (Proper/Secure form submission, writing SQL queries, what is wrong with this code question, unix file handling question, what is MVC) and about 45 minutes of behavioral questions. After this interview, I have been invited to a second interview to meet two senior members of the team. After the second interview I have received a call from the CTO with an offer. I was given two days to make a decision and was also provided with instructions on where to and what to do on my first day.

I was initially emailed and given a 1:1 interview within the week. When I went there, I had to do a short skills test testing my knowledge of SQL, PHP, and whatever else was involved in the position. It was fairly basic and easy and it's a good test for weeding people out. However, I think they should have given the test online BEFORE you actually show up for an interview! Otherwise it's a waste of everyone's time... The person in charge of interviews was the CTO of the company. He was an easy-going guy but the interview seemed a bit unprofessional and there was an awkward silence at some points as he tried to figure out what to ask next. The second interview was better. It was a panel interview with some of the employees and the CTO asking questions related to the position. The employees had very good questions and made the interview more professional and gave a great idea of the work environment. Some of the projects the company was working on were described in the 2nd interview. Unfortunately they are adult-oriented projects and I was only made aware of this in the 2nd interview. This isn't a problem for me personally but there may be others who do not wish to apply for jobs at companies working on those sorts of projects. The people seemed easy going but the multi-cultural atmosphere felt forced, it felt like being in a sitcom somehow, very stereotypical. The office was made up of young people and the workplace was clean with private or small offices.
