Interview Preparation Tips

Round: Resume Shortlist
Experience: On the basis of CGPA

Round: Technical + HR Interview
Experience: I was extremely nervous as this was going to be my first interview as a fresher. Adding to that, their first question was ' who is your favourite basket ball player?' as my CV mentioned that I used to play basketball in school-life. I just didn't know whether I should blabber an arbitrary name or give the honest answer. After giving the latter I was asked how crude oil is seperated from water. I told them that if some time is allowed then crude oil and water will be separated in two layers. Now I dont know why it seemed to me that crude oil having asphalts, coke should have greater specific gravity than water and should appear at bottom. After giving the answer, from their expressions I knew that I had screwed this as well. Now they asked some more teasing questions like why I had joined IIChE, how many meeting I had attended and so on and I don't remember the rest as I was close to tears by then.
Tips: At the end, one of the panelists gently told me 'Please don't be so much nervous from next time'.

Interview Preparation Tips

Round: Technical + HR Interview
Experience: They first asked me to tell me about myself. Then I was asked to briefly explain what I did in my internship at SAIL in summer'16.Then they asked a few technical questions on the project (Modelling of a bio refinery using Indian agrowastes for energy and environmental analysis) that I was doing in that semester under one of my professors. Then they asked me about my favourite subject to which I answered, "Heat Transfer". So they asked me some basic questions on heat exchangers and related graphs.
Then one of the HRs asked me to tell about my career objectives followed by a few other questions like my strength, why CAIRN, what I would have pursued if not engineering,which location would I prefer- Rajasthan(where there is main plant of CAIRN) or Gurgaon(where there is main office of CAIRN but no plant).
Then they asked me if I had any questions to ask to which I asked them a few internship related queries. And this way, the interview ended.
