Audible Software Development Engineer interview questions

Phone interview then In-Person interview with 5 people. In-Person was in Newark. A lot of "Tell me about a time you..." questions. To me, it was a red flag. I suspect there's pretty high turn-over and they are trying to weed out folks who will get frustrated easily and leave. Other questions included more standard design a system for 'X' and algorithms. For the algorithm questions, I was struck by how the interviewers didn't help. For the first question, you have to sort the input which isn't obvious for the final solution; it took me a while to have that 'ah ha' moment and get to the right answer. I think suggesting something like "you can change the input" for a candidate who doesn't see that in the first 5 mins is reasonable. In the last interview, I purposely answered an Order of Magnitude question wrong (as I was no longer interested) then started to work out how the problem was not O(n) but O(S^n) and the interviewer actively discouraged me from my revised answer. Office space was open. I was surprised how quiet it was. You could hear a pin drop. No friendly banter, no water cooler talk. Just silent screen staring. Laptops and screens also looked outdated. I was not offered a position but would not have accepted one if offered.
