Selected Interview preparation journey
Journey
I pursued my graduation in AI and Data Science, during which I completed multiple internships in the same domain. My primary focus was on Python programming and Machine Learning, which helped me build a strong technical foundation. The hands-on experience I gained from these projects and internships played a crucial role in helping me crack the job opportunity.
Application story
The opportunity was on campus. It started with the forms from the Training and Placement cell, followed by an online assessment at the campus itself. Shortlisted candidates were asked to report at the office for further interview rounds.
Why selected/rejected for the role?
Having short notes for DSA and DBMS helped me revise quickly and clear the online assessment efficiently. During the interview, my confidence and freelance experience played a key role in increasing my chances of selection.
Preparation
