Humanism & Electronic Commerce interview questions

A little longer than an hour. Asked a few questions on php knowledge. Nothing really too advanced. Also asked me some questions on Magento, probably would have asked more had I had more experience with Magento, At the end, they had me do a test where i had to write a function to print out a binary tree when given a certain depth. The people who did the interview were great. They were friendly, casual, and the interview didn't feel too formal. I was comfortable, and the interview overall went pretty well. Also when i couldn't answer something, they provided great detail into helping me understand what i couldn't answer.

I was contacted by a recruiter who asked for work samples of apps I have worked on in the past. I sent him a PDF portfolio. Soon after, he set up an in person interview, and instructed me to print out a physical copy of my portfolio. I was interviewed by two people at once. The recruiter advised formal attire, but the interviewers arrived in jeans and t-shirts and the interview itself was a bit more casual than I had been expecting. They were fine with me showing them an app I had created on my own phone, and at one point whipped out a tablet to look up projects I had worked on.
