SoFi Tech Solutions PHP Developer interview questions

Contacted by recruiter on LinkedIn, pretty standard stuff. Did a phone screening, and an on site interview. First I was interviewed by Project manager / Director and Lead Architect. Mostly talked about stuff on my resume. Then interviewed by the whole Development team. Asked me specific things about my experience, what sort of things I had built in the past and different problems I had to solve. Asked me a few questions about lower level PHP development (they are a Zend shop), stuff you might not know about if you have done most of your work within a framework. I thought that was pretty interesting. They also whiteboarded me. Lastly I had an interview with the CEO who asked me to "design amazon" on a whiteboard. Probably just trying to see how much I knew about developing an app start to finish. Kind of an interesting exercise I suppose. Overall I thought the interview process was very thorough, which I liked, but sort of antiquated. I haven't been whiteboarded in a long time, and it was really off-putting and fairly pretentious. I thought it was weird, but after my in person interview, they decided to send me an online skills test and then told me not to take it after all. Also, after extending me an offer, they told me I had to take a drug test... who does this in IT? I got an offer from Galileo which was very competitive and would have definitely accepted if I didn't receive another offer at a company that I decided to choose. Seems like a great company, just didn't end up being a good fit for me.
