oCode Technologies interview questions

Two interview rounds first technical round with all the questions related to the php and work exposure . It was relatively easy .Basics of php . Oops concept ,interface , inheritance . Second round was where I had worst experience . Person who was going to conduct interview did not attended the meeting . I have to wait for 15 minutes . I have to call the HR and she replied me back after an hour . Second time interview was schedule and the person was asking random things why does your stack exchange profile has such low score . This show your not technically strong.
