After months of fierce autumn trick, and finally landed linux development, are summarized some of the autumn trick experience, I hope the students to prepare for next spring or recruit help.
Landlord double non-degree, non-Great God, in July began to resume production of cast, cast net almost 7,80 companies, basically came to nothing, and finally change the strategy, we began to turn from mid-September to attend school lectures will be from fresh raw job Indus app to see if the hold time and place of each company Presentation, a rarity in the field written to the company, this can be written directly after the interview, not the card on a resume, c-grounded written basically can live (listen Juanmian technology officer say you have 100 points 60 on it), and of course online written test is not the same, you might want to line and hundreds or even thousands of people a job with the competition, the difficulty can be imagined, the landlord c plant within six months participated in the written test three times before they get the chance two faces, so it is recommended to run more than preach interview, Guangdong it's class lectures will focus on basic laborers, as well as extensive work. The following is a consolidation of some of the companies interviewed by face
