Journey
First of all, I got selected for a Tier 1 college. From there, my coding journey began. After learning DSA basics, I jumped to Leet code and Code Studio and practised a lot of questions from there. Later, I started with competitive programming and regularly gave contests on Code forces and Code chef. That helped me to build my coding skills and think effective solutions quickly. I tried to solve 5-10 medium to difficult questions on a daily basis.
Application story
De Shaw visited to my campus for the placement. We just had to upload resume and fill all details in the form. First shortlisting was done on the basis of CGPA and Resume.
Why selected/rejected for the role?
I was selected because, I could solve almost all the problems that were asked and I seemed enthusiastic about the role of a Developer. I had done competitive coding, so I was able to answer questions quickly and effectively. My verbal skills were decent and I could deliver my thought process and decision making in both Technical and HR round.
Preparation
Duration: 4 months
Topics: Dynamic Programming, OOPS, Computer Networks, Computer System Architecture, Operating System, Data Structures, Pointers

Coding problem2

A lot of Variants based on Constraints were asked in this Round. They will ask you to write the final code for every question before Submitting it(run all test cases) so you won’t get any hints after running test cases in the IDE. ( So don’t Submit your code before dry running it on a lot of Test Cases on pen & paper , they allow to use pen & blank paper at the time of Interviews) .The Interviewers tried to trick in case of time complexities even if you gave the best one. So try to be confident.
