As posted above, after graduation everyone need to gain experience and enter into manger role. I am working for a big organization for 6 months now . I also have engineers who is experienced for 25 years. They have all knowledge about the work. But why they are not interested in becoming a manager. I asked one of them, He told its is hard to manage a group. The manger is first one to loose the job if something get bad. That means managers have no job security. That may be true. But for me, I really believe i do have a manager skill and i can become a manger after couple of years of experience. What i believe in becoming a leader or manager you should have a good communication skill, management skill, and always a team leader need to be a motivator.
