During on campus interviews back in august, i got 2 jobs, both in power sector. And joining of both has been deferred now by 3 & 6 months. So i went for another interview yesterday in a glass manufacturing company(supposedly covering 70% market share in India). I got the job in plant maintenance, which at the time of interview I declined. I just don't want to go in plant maintenance type jobs, I already saw what its like in a power plant earlier. Since the placement department of my college does not allow me any more chance(they allowed the 3rd one because of deferment of first 2), I can not have any more campus placements. There "might" be a campus visit of a company for mechanical engineering students on 8-9 may. And the glass guys ll be sending offer letter by 7 may. So I was thinking of writing a letter to HR of the glass company that i wont be able to join their company. Is it right to do so? If i don't make it in the next company, i do have a 3 month project in a government research organization, so its a sort of back up. Is it worth taking a risk? Also I am not sure of when the first company will send their joining letter Obviously research guys will be paying far less than the company, but i don't want to have a maintenance engineer on my CV. I think I am being paranoid about it, but i dunno. So the situation is: job as maintenance engineer from 1st July & job security OR an apology letter to glass company & another shot at the next company with a better job profile OR a 3 month project & hope for getting the job letter from Siemens?
