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.

When the transformer operates at half its rated MVA, the current flowing through the windings is reduced.
As a result, the copper loss in the transformer decreases.
This reduction in copper loss leads to improved efficiency and lower energy consumptio
