2. G.D ROUND:
3. Technical round: Any way finaly I entered the technical interview, after coming out I realy wondered, I mean I told all the answers perfectly and in a speedy manner, so u must be perfect in one subject, which u written the best subject in u r resume. One of the technique is they will ask questions from the subject u written as best at the last.
My interview, I entered in to the panel where two members sat, they told me to sit, then I sat on a chair, they asked me which u r favourite subject is? -------MES What is the full form of it? ----mechanical engineering science What is there in it? ---basic concepts of mechanical engineering Which are the chapters in that subject? ----sources of energy, boilers? Tell me the type of boilers? ---fire tube and water tube boilers Tell me the principle?---in fire tube boilers hot gases moves in to the tube bands and cold water circulates among them, where as in water tube boilers water moves in to the tube bands and hot gases sorround on them.( show in actions by hands) Ok very good, tell me other chapters?---power transmission Which are the types of power transmission??chain drives, gears, belt drives, rope drives Tell me the concept of belt transmission I mean principle?--- in belt transmission there r two pulleys, one is driver connected to shaft, because of which it rotates, another is driven which rotates because , driver rotates, on these pulleys we keep a belt to transmit power How it will transfer?---because of slack and tight tensions on pulleys Ok very good, u can go now, we will anounce the results later, ----ok sir
4.H.R. round: It is very easy, it will be carried in jsw only, once if u shortlisted in technical, and if u r records r correct, then u will be selected, don?t bother about h.r round Any way the interview is very much experianced in my life, because it is my first interview.
6. Contact: Any way best of luck my friends, after u r interview; please forward u r experience if possible, so that it helps others, like from me to u. Once again best of luck my friends, Thanking you Yours obidiently Vinayaka g
