Selected Interview preparation journey
Journey
Publicis Sapient came to my college (Birla Institute of Technology, Mesra , Jaipur Campus) during middle of the placement season (2021-2022). I had been preparing for other companies before but wanted to crack this one as they are a reputed name in IT sector. So I began preparing by going through some of the interview experiences on Geeks for Geeks related to Publicis Sapient whichever I could find most recent, Apart from that I went through and practised some easy, medium and hard level problems on Leetcode.
Application story
The opportunity was posted on my college's placement portal which was created for each student to apply if they were interested. So Sapient had their own form as well which also needed to be filled. After filling the form the interview round details kept coming on my email.
Why selected/rejected for the role?
I was able to come up with solution to problems given to me during my personal interview and for a question which I was not able to come up, for it I kept on trying to solve that and did not give up. learning from this instance is that there is a high chance of always facing a problem which you have not practiced but important thing is not giving up and trying to solve it with topics that you know if somewhat related.
I was honest with my answers and which were non technical.
