Lastly, I was asked whether I could live in remote rural areas.
My teacher once said "Keep the handle of your interview is in your hand. Once the interviewer starts driving, it is destined to crash." Take the interview in the direction where you are confident, be it your project or training report. Do not bluff there as it may backfire. It is okay if you say "I DON'T KNOW" to few questions rather than bluffing.
Tips: Be prepared for the normal questions and keep calm in the interview. Many interviewers want their candidate to be confident.

Technical:
50 Qs in 30 minutes. The Qs were fairly on easier side. Just that, Qs spanned all across chemical engineering, with almost equal weightage on all topics. Most Qs were from past years' GATE papers. I attempted around 40 Qs.
Tips: 1. For aptitude, prepare well in advance if you are weak.
2. Strengthen technical by solving MCQs from Indiabix.com
3. Since there are no negatives, go for most Qs.
Duration: 60 minutes
Total Questions: 80

The questions were from whole of the chemical engg like from thermo, mass, heat, cre but not from process control or instrumentation or from chemical technology. Most of the questions were conceptual and are just theoretical.
Tips: For apti, try to solve questions from www.indiabix.comFor technical, brush up ur conceptual knowledge and try to learn more and more of mass, heat, themo and cre.
Duration: 60 minutes
Total Questions: 80
Round: Technical Interview
Experience: Overall my interview experience is good. I gave around 70 percent of the answers. My interview is purely technical but it was not so with my friend. His interview is 90% HR.So u never know what type of interview u r going to face when u walk in there.In my interview the questions were mostly asked from thermodynamics and its applications.
Tips: Be calm and confident.Try not to get nervous.Never try to attempt the questions of which u don't know the answers. Attempting those questions and thereafter not giving answers properly gives a bad impression.
General Tips: As I previously told try to remain calm and not get nervous.If u do so no one can take that job from u.And by chance u don't get selected, then do not get disheartened and just think about ur mistakes and try to improve them as U are the best judge of yourself.
Skill Tips: Do not get nervous in the interview.Do not try to solve the whole technical paper rather go through it and attempt the questions u think u can do.For improving communication skill, try to communicate with ur friends in English. Read newspaper and communicate with urself in mirror ( this method will particularly help u a lot in improving ur communication skills and will also free u from any kind of presentation fears).
Skills: Confidence, Time Management, Communication
College Name: MNIT
Motivation: yeah RIL is a very good company, very large and with a lot of scope.So just go for it as if u want to build ur repo then it is one of the best platform to do so.

All the technical questions were theoretical questions and no problem solving.
Tips: Briefly touch up all the core mechanical subjects and you will be through the test.
Duration: 1 hour
Round: Technical + HR Interview
Experience: Firstly, a form was given before the interview. In the form, they asked us to fill all our bio data, projects we have done and some basic HR questions. There's only one interviewer. The first question was "Tell me about yourself". He asked based on what we have written in the form. He asked about my goals, role model and also about the company. He mostly checked whether I am interested in the company or not.
