Software Recruitment How much Transparent is the process

When i passed out of the college from a premier institute i didnot have any idea how the world will welcome me. But the tag name of my institute didnt let me down. I was placed in a good company with a handsome salary and was happy. I thought it was my talent which got me into such a big company. I was under the illusion that in this IT boom every software engineer in India is placed in some or the other company.

A year later one day i came to know that some openings at my company and then i went forward to send a mail to my college alumni group, informing about the the oppurtunities at my company. The first day i got the mails from the students who were from my college and fullfilling the requirements. But later i got hundreds of mails from people seeking for jobs from some other colleges.

Lets look at this situation from two angles. First suppose that i am candidate who is seeking for a job. I come to know about the openings at some company. I dont think of anything else but forward my resume with a nicely written cover letter. I think that as soon as the mail is sent some one at the recieving end is going to filter them. And i wait for a day or two and see if i get a call for the interview alas i didnt get. What should i do? Should i go and kill myself for not getting a call. Or shall i assume that my resume is not excellent enough for the call. All this questions bugs me for a day or two.

Now lets assume that i posted a job in some website. I get mails from some people. I have an attitude that i will stop forwarding the mails to my HR after i get some 20 mails which fit the job requirements. So starting day 1 with full enthu i open one by one resume scan them and send the best resume to the HR. Now i am done with my work and i close the issue. I wait for the HR to reply back to them. But here matter doesnt end. As i see my mailbox flooding with thousands of mails. How many do i see? I simply do a delete. I dont have to take care about the feelings about the sender. I am just an ordinary man, looking for some kind of benefit from referals. And moreover i cant take all of the mails sort them by their knowledge and give them rankings and then send them. This will take O(n*n) time which no one has these days. I am in a dilemma. Am i making those hundreds wait for their job call, making them feel bad about their qualifications.
