Journey
I was unaware of this coding stuff till my school life. I got to know about the field of computer science in my class 11th. I found it intresting and decided that I will pursue my career in the field of computer science. I took admission in B.Tech CSE and learned the various concepts like DSA and all.
Application story
I got a message in my telegram group about the company visiting our campus for the hiring of SDE-1. As, I was in the fourth year, it was sure that I am going to apply for it. I started preparing accordingly and got selected at last.
Why selected/rejected for the role?
I think I was on point with my coding solutions to the questions asked in the interviews. I provided the optimal solutions and I was giving correct explanations to some theory questions asked.
