CAA takes about 2 months after the last date of applications to conduct the test. so expect test date in end of july or start of august. after that result will be out after about a week of test and interviews will most probably be conducted in september. Interview date depends upon the availability of panel members, it could be held within one week of result or it can take about more than a month. after interview it takes about 2 weeks for appointment letters. i appeared last year but couldn't make it through the interview stage. i appeared at Karachi airport for interview.
