I am Student V, a graduate student advised by Professor K. I am about to take the qualification exam. Your advisor is on my qualification exam. and I would like 15 minutes of your time to discuss your advisor's research.
Let's dissect this e-mail. First, he notes that he is advised by Professor K, who has helped me immensely in the past. I figure that this Professor advised Student V to contact me. I feel like I owe Professor K, so this increases the chances that I will make time for Student V. Next, Student V notes a very specific issue to discuss, mainly my advisor as an audience member in a qualification exam. Finally, the amount of time being requested is very reasonable. This Student V and I will be meeting this week.
My name is Worker A and I m working for Motorola as Software Engg. I was browsing through the GradShitTownVille University research page and found you.
I m interested in operating systems and computer organization areas. But still not sure which one I should pursue. I might want to go for a MS /PhD. I need some information regarding the same. Do you think you can spare some time ?
Let's dissect this e-mail. First, it's very apparent that the author was just "browsing" since he asks no question in particular about me or my research area. He is interested in two different areas, not particularly related to me, and wants general information about graduate school. He obviously failed to note the "Graduate Student Resources" link on my personal website, or he would have found the list of links answering this question. Finally, he is asking me to spare "some" time, but to discuss what? I am not a professional guidance counselor. I replied to him with a list of links, but I did not agree to meet with him.
