I was invited to Brickfest and got a free interview from that. The interview was slightly harder than made expected at Brickfest, but still pretty easy overall (lc medium ish). It was suggested to me that the interview would be implementation-type questions rather than leetcode, but the interview was still leetcode. After passing the interview, I was pretty aggressively pressed by the recruiter about my other offers and interview processes, which reflected poorly on the company culture (few of my friends had this experience as well). I would've done the final onsite to see what they're offering, but the 5 hour total duration was way too long and I'd rather spend time prepping for my other interviews so I dropped out. Interviewers are nice and Brickfest was fun though.
