It was asked to prepare for concepts for the interview and it will be onboard drawing concepts for PHP. Then 1-1 interview was scheduled to go through the questions. It wasn't told the questions was just PHP specific or framework specific and the type of test. The test was reading a question and write a program in a textbox with no support of autocomplete and PHP IDE. The company owner will watch along the whole test to see what you are searching to understand your thinking. If you find the answer by searching the error by mistake then you are out of test but no warning will be given at the beginning regarding what to do and what not to do so watch out for this trap.
