It was 2 months before there was a email from the staffing agency sending the detial job description and asking confirmation for telephone interview. There was 45 minute telephone interview going over the education & professional experience background. Included questions based on the job description, was asked to provide details of practical experience which was related to the Job requirements. This interview went on fine for me then there was a panel interview with the department head and one more technical person at their office. The questions were very technical , focusing on the job requirements, if you are applying for senior technical position than they expect you to have very good handson knowledge on the technology. The setup is pretty big 100 + servers with 100+ applications.
