Php questions were basic if you have worked on php based projects like- 1- which is not a valid identifier? and there were some options. 2- what is function of mysqli_escape_string. 3- what does php_self function do? 4- difference between delete , drop and truncate 5- difference between require and include? so there were some basic questions about php second part was quant that was bit simple- questions on ages,calendars,time and work and time and distance. Keep in mind that whole paper was subjective.. second round was technical interview which was fully based on logic of sql ,database and php. third round was of hr at company process. 1st and 2nd round was held on day 1 only.
