The development momentum of mobile Internet this year is as fast as a volcano erupting. All IT companies lack a large number of programmers, and programmers’ salaries have been rising this year. With the impact of a series of factors such as the difficulty in finding employment for college students, software companies have increasingly higher requirements for recruiting IT talents, and their requirements for programmers The requirements for employees’ technical level are higher. So after graduation, college students will choose the training industry to strengthen their skills and improve their core competitiveness, hoping to get higher salaries through their own efforts. The brothers are favored by many college students. The reason is because the brothers have made learning a concept of habit and a strong learning atmosphere that makes students feel that this is a real institution to run schools to educate. Five months of study and abnormal and strict teaching methods can cultivate students' firm perseverance and improve their learning ability and self-discipline. It has laid a solid foundation for the development of students. This method has gradually been accepted by more and more companies and students. For those graduates whose current employment situation is not ideal, it can help realize their dream of joining well-known companies. This is also a band of brothers. The reason why it is well received by the majority of students and cooperative enterprises.
A good workplace employee can not only face various pressures, but also have the courage to take challenges. After graduation, every student who comes to Band of Brothers thinks that studying in Band of Brothers is so "difficult"? Has anyone seen a project manager working on a project at two or three in the morning? Has anyone seen someone stay up for three days to complete an online project, only to be forced by the teacher to leave the classroom? The students who graduated from Band of Brothers have such a spirit of daring to fight, because they are not afraid that you will not work hard, but they are afraid that people who are better than you will work harder than you.
Therefore, surviving the Band of Brothers is a success in itself. Only those who have experienced hardships will be calm and calm in the face of big difficulties. They gradually enter the enterprise and become a new force at the grassroots level. With their unique advantages, they will be able to overcome difficulties and surpass themselves. Soldiers who have experienced hundreds of battles are never afraid of the enemy because they are already invincible.
