Talk about previous projects, what technologies are used (language, framework, etc.), since I have a project portofolio site, the interviewer played around with my projects and asked me to debug one of them (oops, I didn't know I had a bug in that app before the interview, so if you guys want to showcase your work, make sure they are bug-free OR know how to debug them instantly). The interviewer also asked about front end frameworks like Angular and Backbone (since I used both for my projects), and Django (I used in my previous work). The questions aren't really technical, mainly about what can be done easily using these frameworks compared to hard coding yourself. The onsite interview lasts a bit longer, in which the interviewer explains their business and asked me to make a simple web app that is specifically for their use (mainly javascript).
