There was a phone screen with the recruiter then a couple days later I had a video conference with a researcher at facebook. The recruiter gave me a lot of great information about what to expect from the process, which was pretty accurate for the stage I got to. The recruiter read off a list of research methods and asked me to indicate my level of knowledge for each. The recruiter mentioned it was important I be honest about how confident I feel with each method. That statement made me start questioning my competency on some of the methods I'm not as strong in, when in reality I am an expert in all of them. I feel like the way the recruiter asked the question was meant for the candidate to second-guess their competency. The video conference with the researcher was a little nerve-wracking and also messed with my head. I have several years of research experience, but the researcher asked me two hypothetical questions (which I wasn't expect to be asked until onsite interview stage) and while I was answering how I would solve a research scenario, the researcher kept a straight-face and probed with follow up questions that made me feel like I was answering incorrectly which of course made me feel less confident about my answers and I'm sure that came across in the interview. I should mention this was my first interview in over two years and I was a little nervous, so this could be why I didn't do as well as I thought I would. I have interviewed at Google for a user researcher position and wasn't asked hypotheticals until I was onsite. I was allowed to work on the white board and had more time to answer them. I was surprised to get these types of research scenarios in a phone interview. That's the main reason why I think it was difficult.
