Interview preparation journey

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 started 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 development but even then I keep on revising the concepts.
Application story
I was practising DSA on a regular day when I saw a small advertisement kind of on leetcode. I opened it and I got to find that company is looking for some fresher graduates to serve as SDE-1. I applied to it and after three rounds, I was selected.
Why selected/rejected for the role?
I was rejected because I was not able to write optimal code solution for the coding pronlems asked in the technical interview.
