Idk

Recently solved OA for Amazon, (i think it was for an sde 2 role....the career page just mentioned SDE and requirements had 2-3 years of exp.) But man was the OA hard - 2 questions in 90 minutes. And two more sections - Work Style and Work Simulation The time is one constraint. The second is optimizing the solutions. Brute force isn't going to cut it. The latter is the hardest part. They ask you questions using approaches you wouldn't have even thought of in the first place. I can safely say I bombed the OA (don't even ask how many i got right). Any tips on getting better would be appreciated!!
