If it helps, I did like 2 easy leetcode exercises and still got into Amazon lol. I've done nothing but business applications for my entire career, so I don't know jack about data-structures nor algorithms. Most of the interview is about your work history and "leadership" questions.

EDIT: btw Amazon is NOT a good place for busy parents IMO. The on-call rotation can be brutal. YMMV based on where you land in the company, but if they will try to sell you hard on the positive aspects of the company and downplay the negatives, so beware.
