TechInterviews.com will pay you for quality submissions. Over the months we’ve developed a pretty good bank of questions and a lot of people volunteered their own. Recruiters and job seekers around the world use TechInterviews.com as good resource for compiling their own interview question banks.
What we will pay for. Quality submission of 25-40 questions with answers provided on any topic related to tech company interviews.
How much will we pay? $5 for a single set of questions with answers. $5 is payable via Paypal or Amazon.com gift certificate.
What will not be paid? Plagiarized submissions. Submissions with incorrect answers. Submissions with questions already covered on TechInterviews.com (hint: use the search engine). Submissions violating copyrights.
Where do I start? Send an e-mail with the question-answer set to moskalyuk@gmail.com. Within a week you will get an answer from me, basically saying yes or no. After some editing job your set will be posted on TechInterviews.com. The question set must stay on the site for a month, and then you will be sent the Paypal payment or Amazon.com gift certificate. Having the set published for a month allows me to make sure it’s not plagiarized and I don’t get nasty lawyer calls for violating someone’s copyright. After a month, check out your inbox, a Paypal payment or Amazon.com gift certificate will arrive at that address.
Can I promote my submission? This site’s revenue is being dependent on advertising. Tell your friends and colleagues about the site, ask them to visit it more, and this way the revenues will be increased.
Disclaimer: I reserve the right to stop this program at any time, which would basically happen when I run out of money, i.e. will have the site bring in less revenue than I pay out to submitters. Currently I can handle 5-6 submissions a month, so be sure to send yours early.
