Viridien Web Software Developer interview questions

I applied through the career fair at the University. I was contacted by the company HR to schedule a first round which was technical round for 50 mins. I was given to solve around 8 to 10 questions from various domains like SQL, PhP, JavaScript, Brain teasers, Servers, basic maths and coding questions. This round is easy and checks overall knowledge of software development. The second round was onsite interview with a software engineer. I was asked to solve 2 questions. One of them was strictly PhP based and the other was using Web technologies to show and manipulate graphics on screen.

The first step in the interview process is a remote questionnaire. A time is scheduled in advance for the 50 minute questionnaire. There were about 12 questions in 3-4 sections - logic/intelligence, php, mysql and servers. A webex session was setup so that your computer's webcam would watch you as you completed the questionnaire. The questionnaire was a Word file that the interviewer sent by email. After your 50 minutes are up, you return the questionnaire via email to the interviewer and the webex session then ends.
