Journey
Working for an MNC was something I always looked forward to, and an interview at Amazon was an on-campus opportunity for me. Road to start practicing coding in the middle of sophomore year. To see what my coding skills were like, I started doing basic problems on various portals, including Coding ninjas, Leetcode, Gfg. However, at that time it did not solve the core problem of DSA. Then I started following a YouTube channel with about 150 issues specifically created for placements and internships. Which YouTube course or channel you choose is up to you. In my fifth semester, they started hiring a company for our industrial semester.This was the first one I gave them.
Application story
This is an on-campus opportunity open to students with a GPA of 6 or higher and a final selection will be made on the CGPA.
Why selected/rejected for the role?
I was selected. The interviewer was impressed with the work I had done in my internships and understanding of the frameworks I had used in those internships.

Tip
Tip

Tip 1 : Problem-solving Ability, how to approach a problem, they will tell you to write the logic of the code(most optimized).
Tip 2 : Practice coding from any platforms like leetcode, GFG (solve easy and medium level questions)
Tip 3 : The major shortlisting is done in the first round that is the test(MCQ and Coding) so prepare CSE fundamentals very well (especially networking(all types of protocols like TCP/IP, DHCP, SIP, etc) , JAVA, real applications of data structures, software testing)
Tip 4 : Linux basic commands.
Tip 5 : Mention at least 2 projects which you know very well. Topics like ML, DL make a higher weightage.
Tip 6 : Communications skills should be strong.
