Journey
I started my coding journey from the second year of graduation. I asked and consulted seniors on how to start in my career. I started doing DSA. In starting it was not regular but from the seventh semester, I started practicing DSA on regular basis. Meanwhile I also learned Web Development in the last phase of third year. Than, I was ready to apply in different companies.
Application story
My friend texted me about this company visiting our campus and told me some of the important questions and topics for its selection process. I applied and participated in its selection process and luckily most of the questions were from the list of important questions shared by my friend. So, I was lucky here.
Why selected/rejected for the role?
I was confident during the full interview process. Actually, I worked a lot on my communications skills and I think they were the main reasons for me getting par the selection process.
