Hello guys, I know you’ve come here all the way for your placement preparations and most of you might even be preparing for the same SRE role at COHESITY. So, before I take you through my study tools and tips I wish you all the very best for all your future endeavors. So, so let me give a short and crisp introduction to the company that I’m joining.

And now the part that you’ve been waiting for:

• I along with 182 of my batchmates applied for the drive and prepared for the aptitude rounds. We had our Online aptitude test on 22nd Aug 2021 and on 25th we were given the shortlist. Only 13 people were shortlisted including me. We shortlisted students who had a pre-placement talk on 26th August. During this talk when the Q&A session began, I asked 2-3 questions in between( This is very important. You’ll know why as you read). Then we waited for the interview dates to be announced( Waiting was the worst part). Finally, we got to know that our interview was supposed to be on 2nd Sept 2021. I was preparing completely for all the remaining time that I had(I’ll share the study tools below). On 2nd September morning, 9.40 am I had my first round, and then a few people were qualified for the next round including me. I had my second round at 12.35 pm and it lasted up to 1.15 pm. After this, I really felt nervous and scared, to be honest. On 3rd September in the evening, we got to know that only 3 students were selected for our college. I was one of them and I am really thankful for my parents along with my family and friends for their support. I am really grateful to GOD!
