Yeeeaahhhh, a legal support company found me on LinkedIn last year b/c of something in my resume that was key to this case and they were like, "Hey, would you like to be an expert witness and interview with this firm for a case? Shouldn't be more than 10 hours or so of work." Naively I said, "Sure that sounds like fun." And the firm interviewed me and hired me and now I've billed who knows how many hours (I mean, I do, but whatever) staying up until 3am writing analyzing data, writing reports, and have to go testify. It has been amazing and I got a job offer out of it, the expectations were just way out of line with reality because it turned into WAY more than 10 hours.
