One dilemma I am in is regarding the Letter of Recommendation :
Apart from the LOR from my immediate manager in the company that I work for (full time), I can get a Letter of Recommendation from a senior manager (2nd to CEO) of the only Copper mining company in India. I have interacted a lot with him over past 4 years for my family business and he will surely have a word or two of praise for me.
Would it be okay to take a LOR from him ?
(One from my manager and one from him)
I think your 2nd recommendation sounds like a good choice, since you already have your immediate manager (if you didn't, I would think differently.) He will give a different perspective than your immediate manager.
I think people forget that you want to use your recommenders as a strategy as well. You don't want both of your recommenders to say the exact same thing--candidate is great, hard working, etc. You want them to give different examples, different stories, different perspectives of your strengths and weaknesses.
