I have a friend who is showing up for a evaluation today.
He will be given a simple php programing question.
He or I will send you the question, you need to solve the question and make a working program for it as soon as possible and mail the solution to him at the email id I will provide.
His evaluation is of 30 min only so you will need to get this done under 30 minutes.
The only catch here is that he is located in USA so you'll have to get up at around 4:00 am in the morning tomorrow to do this job. If that is possible for you please bid and we can talk more.
I am attaching sample questions for you to gauge the level of questions that will come and see if you can handle them. It's pretty simple and anyone with hands on experience with php should be able to do it in my opinion.
