Catchpoint Front End Developer interview questions

From my submission of the application to the phone screen took about 10 days. After the phone screen to the on site interview, it took about 2 more weeks (they do not reimburse travel fees for the interview). The phone screen lasted about 15 minutes and asked some basic questions about my resume, such as: what is your favorite project, what is your least favorite project, what are you currently working on, etc. There was a short quiz during the phone call: 1) What is the difference between a stack and a queue? 2) What is a circular linked list? Make sure you clearly and concisely say what you mean. I tried to simplify my answer since the interviewer was writing it down, but apparently it was not the answer they were looking for.
