This meant that i 6.(...would spend...) just three months in the production department and then they 7.(would move..) me to marketing. Since then, I 8.(have worked...) in three different divisions of the company and I 9.(...did...) an overseas posting as well - I 10.(...was) assistant divisional manager in Venezuela for six months last year. The company 11.(...encouraged) me to continue training, and last months I 12.(...did) my professional exams and 13.(..became) a member of the Institute of Chartered Engineers.
