Answer:
This year our college kicked off placement season with the Amazon. We got the job description(JD) before the placement process. We got good news that Amazon have increased total CTC. With this good news it also added tension and pressure.
Day 1: Coding and aptitude round
Coding round was at 5pm so from morning I had revised very basic things like sorting techniques, B Tree, AVL tree, finding the power set and some DP questions.
Online coding exam was of two hours and was on HackeRank. There were 20 multiple choice questions and two programs. Multiple choice questions were GATE type questions mainly from OS, data-structure , algorithm, database and C. My plan was to attempt these questions as early as possible and starts programming but questions were lengthy and it took 30 mins. After 30 mins there were 3 to 4 questions which I skipped and started programming.
