I am currently a 4th year undergraduate at one of the new IIIT.
I started my DSA journey on 19th Dec 2021.

-> I started quite late with coding as I was a development guy back till 2021.
-> I had learnt C++ and Python due to my coursework of the college.
-> I was doing some basic DSA at GFG using python but was not quite good with that.
-> Cracked a summer internship at one of the Microsoft Subsidiary with my dev skills.
-> Was not satisfied with the internship and decided to learn and practice DSA.

1st Phase(December to April)
-> Practiced and learned some of the basic Data structures.
-> Gave contest regularly on leetcode and started with Competitive Programming.
-> Practiced through Striver Sheet which helped me to clear the basics and then advanced to some medium and hard data structures.

2nd Phase(May to July)
-> Gave regular contest on codechef, codeforces and leetcode.
-> Did my summer intern during this period.
-> Gave a lot of virtual contest.
-> Reached 4* at codechef.
-> Reached specialist at Codeforces.

3rd Phase(August to December)
-> Not able to sit for campus placements.
-> Reached 1963 at codechef.
-> Reached 1563 at codeforces.
-> Reached 2093 at Leetcode.
-> Gave an off campus interview at FAANG but bombarded the last round.
-> Gave 2 off campus interviews in December and cracked one.

Tips
-> Be consistent.
-> Give contest regularly.
-> Don't cheat yourself.
-> Practice mock interviews.
-> If have time practice cp and give virtual contest.
-> Start early.
-> Do peer programming.
