Limeade Front End Engineer interview questions

Found the job through LinkedIn and applied on their site. Got a call from HR recruiter, chatted a bit, and he sold the company to me pretty well. Asked me for compensation preference, which already at this point is a red flag (means they're looking on the cheap side). However, I said I was interested, and he scheduled a call with one of the senior software developers. This was about a 1 hour call. Asked all sorts of technical questions, mostly easy stuff that every Front End Dev should know. I was invited on-site for an interview. Pretty much destroyed the interview, but didn't get the offer, probably because they found someone cheaper. Recommend asking specifically what their salary ranges are, so that you don't waste 5 hours.
