Journey
I took admission in tier 2 college for B.Tech in Computer Science. Firstly I planned that I will start learning DSA from the first year but I could not. So, I began practiced DSA from the fourth semester, and along with DSA, I also learned development because that is what I wanted to be. By the end of Third year, I was confident in both DSA and web development but even then I keep on revising the concepts. Firstly, I was placed in a software company in Gurgaon but I wanted to get into a well known organisation so I keep on doing DSA questions even after getting placed.
Application story
I got mail from the HR at Delhivery that they wanted to hire some candidates for the post of SDE-1, and if I wanted to apply to it, I just had to share my resume with them. As, I wanted to change my company, I mailed him my resume and proceeded in the interview rounds.
Why selected/rejected for the role?
I think my skills and knowledge were up to the mark, that they found me as a valuable candidate. Moreover, my communication skills added up to my numbers.
