It was my first interview there. The security of the office is supper tight. I have to wait 25 min outside in the street as I went there 30 min prior! The primary selection was in written test. Total marks was 30 and time was 30 min. Most of the question was analytical and SSC level math. I had to write a broad question on "Current situation of compliance of the companies in Bangladesh". One have have to be fast in solving math problems to do well in this exam. NO Calculator NO cellphone.
