Amazon interview suggestions

I meant any system design related questions? I am only studying obj oriented questions, is that sufficient ? Or do I need to read about distributed systems , scalability etc too ?

System design is important and kinda decides your level (between L4 and L5). You can start with Grokking the System Design Interview and then dive deep into the terms you find in those articles.

This will be the most important/unpredictable part of the interview. Algorithm/data structure questions aren't that difficult compared to other companies tbh

Agreed

We cannot/should not generalize from your experience.

Im not, mos sde2 are a joke at amazon and should be sde1!
