I understand that Amazon has a SD interview round for all levels from SDE1- SDE3. I have interviewed with them before and from hindsight I can tell that they focused more on LLD when they asked the design question. (And I was not prepared for that)

I have onsite with them next week and I want to understand is it reasonable to assume that for SDE2 level when they ask a design question they are looking for OOD and not actual HLD?

I am asking because preparation for both is going to be very different and I want to concentrate my efforts more on one of these.
