Foreword

Now, for the technical staff (soft opening, algorithms, etc.) written in the job search process is essential (except free written test, most people need written), written while the general composition is selected, fill in the blank, short answer, the programming problem (this part is very important), so brush theme is essential; for graduating students job search needs more crazy brush problem, because usually have their own research tasks, but it is recommended that individuals should brush problems step by step , prepared in advance, so that you can compare easily deal with this part of the programming problem, rather than focus only on the question brush it every day; for people who have to work does not mean that no longer need to brush the question, and will even quit there are questions of assessment algorithm, so both for fresh graduates or serving officers, finding a job requires some arithmetic ability, in order to reduce the occupancy time each day to brush the question, then we can do is brush the problem early layout tasks, will come to work prepare in advance, so even if only a question every day, according to count approximately 1 to 2 years time job, so when looking for a job at will 300 to 600 of the subject.
