Ask HN: Should I participate in campus placements?

I am from India and currently doing my masters in the top engineering institute in the country. I am about to finish my masters and most of my colleagues are getting ready for campus placements. I am in a big dilemma. I had two years of work experience before I entered the college. No placement company gives any additional benefit for the same. (90% of students don't have work experience so companies take other for granted). While studying I have done following things 1. Developed a highly appreciated webapp for a top hospital in the country. 2. Co-founded a startup and its going on well. (though I will be out of it soon) I did all the development and maintenance. 3. Worked on a defense related project 4. Developed a portal for Education ministry and administered over 20 small projects related to it. I personally feel I have got a lot of experience which most of the companies will not appreciate. Most of them still use C programming to test programming knowledge and involves programs like reversing a linked list. I am a python/php/ruby guy. Hardly any company visits the campus aiming to hire web developers. Most of the recruiters are large banks which will pay a lot but put me on some .NET/J2EE project. However there is a lot of pressure on me that a bird in hand is worth two in the bush. Everyone says why risk finding a job in open market when a high paying job awaits you through placements.
