Amazon SDE I Intern interview questions

Applied through campus career fair in university and got called for 1:1 on campus interview which lasted for about 30 minutes. Questions asked were mostly design questions, and a few technical questions from projects on your resume. Scalability is most commonly tested during interviews. Interviewer provided helpful hints wherever needed

I applied on the university career website. Got a call saying they are interested in interviewing me. Setup two interviews for a scheduled day. First person dint call as I think he couldnt connect, or got busy. Second interview went smooth. He asked me to write a simple program, swapping two variables values. Then asked about linked list, hash-maps, pros and cons of each, time complexities. After a week second interview was setup, he asked questions on similar lines. Like, writing a code to reverse a string, discussed time-complexities, different sorting algorithms, and different data structures. Got a call after a long while with an internship offer.
