Selected Interview preparation journey
Journey
I did my B.tech from DTU in 2021. As I am always passionate about programming I thought of enhancing my skillset by doing DSA course in C++ from Coding Ninjas. I found the course to be very helpful in preparing important topics for interview in a short amount of time.
Application story
I got an email from Publicis Sapient hiring team with a form link. I filled the form and then later got a HackerRank test link. After that there were two rounds of interview and finally the job offer.
Why selected/rejected for the role?
I was selected because the interviewer was impressed with my ability to create a modern website on my own. Also they found my basics of operating system and computer Networking to be clear.
