I like the clean design. I also like the concept. I had done something similar with pen and paper during my searches, but it never quite kept me up with who I had talked to and when.

Is there a feature to remind the job seeker of upcoming interviews?

I'm not sure about the "selling" of the site right off the bat. This is a good niche to be in for revenue. Possibly you can match seekers with jobs proactively, let contextually relevant ads and targeted banners serve up high-paying clicks and impressions. Then find a way to charge for "premium" services.

What language/framework did you use to create the site?
