Interview Preparation Tips

Round: Group Discussion
Experience: Most of the questions were related to coal geology and structural geology like coal grades, deposits in India, their main use, i.e. whether coking or non-coking grade and sedimentology.
Tips: Don’t hesitate to speak anything. Be brief and to the point. Good analytical ability and of course oratory ability is required

Round: Interview
Experience: Geological as well as some HR related questions can be asked.
Tips: Be confident and if you don’t know an answer do not beat around the bush.

General Tips: For written test R S Agarwaal aptitude and reasoning is sufficient. For Technical, whatever is studied in curriculum is sufficient. Also project and internship parts should be well known. At last One thing one should keep in mind that one has to sell oneself so do whatever you think can describe yourself and that will be beneficial for your customer(company). All the best for all the participants from my heart and soul.
Skill Tips: CGPA as well as results in secondary and senior secondary levels matter. Government companies do not prefer candidates who have gaps in their academic career. Not necessary for students in Geology but good field knowledge and intepretation capability of structural maps do play an important role in the selection process. A bit of knowledge about the industrial scenario is required. Many of the students could not even define ‘dip’ and ‘strike’. So I think a solid base in structural geology is required to join a mining company.

Round: Group Discussion
Experience: They shortlisted some 40 students based on their CGPA in the respective categories, after coming to campus there was a GD out of which some 17 people got selected.

Round: Other Interview
Experience: Then there was a Personal interview and 10 got selected at the end.

General Tips: It was a wonderful experience knowing half of the things not knowing quite some of them and finally getting selected. One thing I knew I did not fake around with any of the question. Guys Never feel bad if not selected, because it is not destined for you. there is something better waiting for you.
Skill Tips: No extra preparation required just the normal notes of class and wherever doubt existed got it cleared from NPTEL videos they were really helpful.Be confident in whatever you know. Don't take any tension about whatever you don't know as you cannot change anything regarding that. Never beat around the bush. Be straight forward. Always go with a smile come back with a smile and be Confident. Confidence matters a lot.

Interview Preparation Tips

Round: Group Discussion
Experience: Selections are based on pointer, there is a GD.

Round: Other Interview
Experience: Interview Round (technical and HR both). People who are interviewing want to see whether you understand them or have just mugged up. Projects which might have done is also important. Contrary to the popular belief, pointer matters period. Don’t try to fake, interviewers are good at catching them and then screwing you over because of it, just be honest.
Tips: Know your abilities and when asked about something which you know nothing of, answer truthfully. Please have a shave before coming. Remember you are selling yourself. Everyone's extra nervous on their first interview, it gets better with experience. If you have messed up one too many interviews take a time out and think about it, talk with your friends, get honest feed back and build on it.

General Tips: I'll stop now with a quote. "Do not disturb yourself by picturing life as whole; do not assemble in your mind the many and varied troubles which have come to you in the past and will come again in the future, but ask yourself with regard to every present difficulty: 'what is there in this that is unbearable and beyond endurance?'
Skill Tips: Be through with the basics, I cannot emphasize the importance of this. Placements are full of stress, anxiety, rejection. So in those times don't start any "habits" which you might regret later.Try meditation it helps.

Interview Preparation Tips

Round: Group Discussion
Experience: GD- Mainly they divided trical candidates in two groups. 1st containing sc and st candidates, 2nd had general and OBC and around 35 people in 2 groups. 14-14 candidates each turned up for GD. They gave engineering related topics- for first group engineer as politician and for 2nd energy audit and engineers role in it were the topics. every candidate is given 2 chances to speak. 1st everybody is asked to pitch their own ideas and thoughts. again the invigilator will ask you to add any relevant points if you want. Finally they will ask one of you to summarize wholediscussion.
Tips: Just speak relevant things, don't try to sell fake facts, they will catch you. and whilesummarizing don't add new points,stick to whatever the group has already discussed, theywere adamant about it. one of our group mate got scolded in spite of speaking very goodbecause he brought incorrect fact and while summarizing tried to add new point.

Round: Other Interview
Experience: For me it was kind of stress interview. One of the panel member asked me the question even before asking me to sit. After greeting them I tried to answer the first question, but he was ready with second question. both the questions were regarding transformer protection. I explained buchholz relay for transformer protection with diagram, they asked about other ways of transformer protection, I could only explain one more method of over current protection.They said explain two more, but I couldn't. Afterwards, they asked me about types of circuit breakers and working I answered them 50-50. advantage of HVAC transmission I told. After that they asked me random questions like material used in transmission, material density, comparison between different material for transmission based on resistivity, cost and density(I was not able to answer most of them, and I was stressed out), suddenly everybodystarted asking questions (4-panel members), I took my time, and most of the time after taking considerable time for answering difficult question I  would tell I don't know. When questions got exhausted they asked me which subject is my favorite, and whether I have any knowledge of management,  I told mathematics is my favorite and for management I had taken 3 optional EE, MTP, MM. they asked about basic definition of management, bernoulliequation for liquid,and Archimedes principle of floating body (I don't know why).
Tips: Keep calm and take your time, even if the ask too many questions at a time, and say no if you really don't know the answer. Finally HR asked me to briefly explain all the projects I have done(15 minutes)

General Tips: Nothing specific, don't give up even if you don't know A single answer. I couldn't answer more than half the questions. Try to use pen and pencil to illustrate the things which you can't explain with words and please never sell fake facts in core job interview, if you don't know, say so.
