Selected Interview preparation journey
Journey
During my B.Tech, I started practising coding questions and participating in interview mocks. I made a todo list on a daily basis and covered topics according to the list. This helped me ensure that I don't miss any topic. I practised questions from Code Studio and Interview Bit mainly. For core subjects, I referred to Gate Smashers youtube channel.
Application story
This was an on-campus opportunity. I applied through the college placement cell. The first resume shortlisting was performed. After the online test 15 candidates were selected for interviews.
Why selected/rejected for the role?
The basic reason for my selection was my strong knowledge of core DSA fundamentals and my problem-solving ability. Moreover, I was confident while answering every question. I think that was one major reason why the interviewer was impressed with me.
