After missing the train from Delhi, somehow I managed to arrive at interview venue on the same day of my interview. My GATE 2022 rank (AIR-1244, Score-591) was not good so I was little bit depressed also, as BARC was the only chance which I had then.Fortunately, one of my college friend also had interview on the same day. I used his room for refreshment. After document verification I went to the battle ground (11th floor of NBH). There my chance came in the second half of the day i.e. around 3 p.m. I didn't discuss any question with earlier candidates, as I had assumed that I wouldn't get selected.My turn came...Me- May I come in sir?Chairman- Yes, you may.They asked me to sit. As I mentioned earlier that I had assumed, I won't be selected here, so my mind was free. Still a little nervousness was there as it was my only chance for the year.Chairman- You are looking very tired?Me- I told him the story of my missing train.Chairman- Ohk, we won't ask you too much questions, as you are looking very tired. Write down your favorite subjects.Me- I wrote down Thermodynamics, Fluid Mechanics, Heat transfer, and RAC. One thing you should notice that I didn't write Heat & Mass transfer, because my senior suggested me not to write Mass transfer as they ask mass transfer very rigorously.Chairman- Asked one of his committee member to proceed with thermodynamics. In the mean time he was studying my resume, mark-sheet & all.Member-1- Which type of compressor consumes minimum work? Isothermal, adiabatic, or isentropic?Me- Promptly said Isothermal.Member-1- Prove it?Me- I made the P-V curve, and calculated the area under the curve. Hence proved.Member-1- Physically prove it.Me- I have taken some time, write equation of 1st law of thermodynamics, then give my answer that in isothermal the work is consumed only to raise the pressure, while in adiabatic, some work has consumed to raise the temperature also.Member-1- Good.This word gave me too much confidence. Now, I was playing on front foot. After this from thermodynamics various questions were asked on Rankine cycle and Brayton cycle.Then comes the heat transfer topic. Member2 had already written some questions on A4 sheet related to temperature profile of a cylindrical body with insulation. I made the profile, in each profile he asked me the reason for that type of nature of the curve, I proved many of them. Member-2 was also asking the questions related to RAC, he asked me to explain the Vapor compression refrigeration cycle. I explained and also made many mistakes, each time chairman corrected me, and motivated me. My engg project was in RAC, so I explained that also. This gave me some edge.They didn't ask too much from FM, simple questions are there related to buoyancy forces, pipe losses, Hagen–Poiseuille equation etc.Chairman- You have written all the subjects related to thermal only, we want to ask from design also.Me- Ohk sir.Member-3 was ready with questions from strength of material. Questions related to SFD and BMD are very important. She asked me to draw the SFD, BMD of various load combination. I have drawn almost all of them. She again asked to draw me the shear stress distribution for I-section, after I made the distribution she added another difficulty that, can we use it like H-section, and also justify your answer. After getting hints and motivation from chairman, somehow I made some justification.Then comes the question of chairman, he asked questions from shaft design. I have answered all the questions of chairman.Chairman- Ohk young man, you can leave now.Me- Thank You sir.It was 4:30 p.m when I came outside. I have spend 1.5 hrs inside and didn't fell that. After removing my tie and folding my shirts, I moved toward the lift for going home.Suddenly, a voice came that chairman is calling you again. I was afraid, because I didn't want to face them again. But, life changing moment was waiting for me.Chairman- Well done Nirmal, you are most probably selected. And gave me the white slip.Me- Thank you sir.I was not expecting this. I was crying there. That was the best moment of my life. My hard work paid me. I got very good grades in interview.After submitting some documents in HBNI, me and 6 more selected students of the day were officially given a tour around the barc trombay campus. After all these stuff I called my father and gave him the good news. First he didn't know that I was in Mumbai for interview, then he also didn't know too much about BARC and job related to BARC.Finally, I boarded the train for home without ticket in general boggy. I couldn't sleep whole night, as I was not believing that I have got selectd.Some suggestions from my experience-1) Don't go inside with too much expectations. As it may bind you.2) Try to make an honest attempt to all the questions, because these are the questions from your favourite subjects not of the interviewer.3) They will definitely give you hints whenever required. So try to make something from their hints. They are very supportive.4) Questions asked by chairman is important, so listen the questions carefully and answer with school level concept I.e don't go in advance level.5) Don't use unnecessary new terminologies while answering a question, this may lead you into the new topic.Keep calm and play your game.All the best Note- I am little bit slow in English. You will understand after reading my answer. Apologize.Edit-1: I have mistakenly written more work instead of minimum work in my first question.;"";""
