does amazon ask object oriented design? or it is most likely system design?
System design for SDE II and oo design for SDE I
What about SDE III?
Same
Was it normal loop or hiring event ?
Depends on what hiring manager on loop wants. I'm a BRiT, I tell HMs that I don't recommend interviewing for OO design. We're not likely to get good data out of it. In practice, those interviews evaluate if the candidate has worked with a large object-orientented Java code base. Not all candidates have that experience, and not all roles at Amazon require that. If HM wants it anyway, then it's usually a simple modeling question. Like a chess game, etc.
Yea, OO for all levels. SDE1 you will do a round solely covering OO. For 2/3 the system design round includes OO
I was asked OO Design for SDE3 loop
Oops sorry I can’t remember!
