I was interviewed on-campus
at NIT Surathkal for
Coal India Limited
Group Discussion Other Interview
Group Discussion Topic
'Engineer as politician' and 'Energy audit and engineers role in it'
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.
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.
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).
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)
- V.K Mehta - specifically protection,
- circuit breakers and power transmission part.,
- Ashfaq Hussain - machines,
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.
