I received a phone call and was asked some basic interview questions by a recruiter. I proceeded to schedule a secondary interview, but I never heard back from them. I followed up but received no response.

Very competent interviewers. Be sure you know the "tricky" algorithms and "big O". A very positive, though unsuccessful, process.

Phone call and in-person meeting. The phone call involved simple "get to know me" questions. The meeting was more focused on my technical background and design-related questions. They were quick to respond and polite.
