Back then, I stood in the corner like a rogue. Now I stand at the peak of my life and overlook the world. I will share with you some skills of embedded job search.
I: Mr. Dafang, a graduate student in electrical engineering, familiar with hardware, STM32 microcontroller, and embedded Linux.
foreword
Below, I will share my own learning and autumn recruitment experience with you. If you have any mistakes, please point them out, hoping to help those who are confused.
Chapter 1 Personal Profile
1.1 Personal background
I have both undergraduate and postgraduate studies in Shuangfei colleges and universities (one ordinary one), majoring in electrical engineering, CET-6, and have the second-level C language for computer and the second-level MS Office advanced application certificate for computer.
During the undergraduate period, there was no personal opinion. The author learned what the school taught. The computer aspect is limited to being familiar with the C language and understanding the 51 single-chip microcomputer. During the postgraduate period, I mainly did some hardware and STM32 microcontroller projects with my tutor, and embedded Linux was self-study. During the first semester, I mainly used Altium Designer to draw circuit schematics and PCB boards. In the first semester of the second semester, I learned STM32F1 microcontroller to write C language programs. The second semester of the second semester and the last semester of the third semester mainly taught myself embedded Linux, and there was a period of four Months of internship experience on Linux platform. In the process of self-learning embedded Linux, the learning experience of single-chip microcomputer has played a very good role.
1.2 Job hunting experience
The author started to submit resumes for internships on April 1, 2020. By the end of April 15, 2020, a total of 10 companies had been delivered. After receiving internship offers from three companies, I chose one of the Linux platforms and practiced for four months. Proficiency in using Source Insight, Xshell, secureCRT, Beyond Compare, MobaXterm, notepad++ and other software at work, these softwares are a must for embedded software engineers.
The author officially started to submit resumes for autumn recruitment from July 1, 2020. By the end of September 1, 2020, a total of 90 companies have been delivered, both in advance (June-July 2020) and formal approval (August-2020- October), as well as some state-owned enterprises and research institutes.
For delivery, you can go to the company's official website and recommend Niuke.com's [School Recruitment Schedule], which is very convenient, as shown in the figure below.
The author delivered a total of 90 companies in the autumn recruitment, gave 40 written tests, and finally 20 companies gave interview opportunities, and finally received 8 offers.
1.3 Job search results
After various failures, I finally managed to reach the Offer link of 8 companies: Xiaomi R&D post, Zhejiang Dahua R&D post, MediaTek R&D post, Foxconn R&D post, Gree R&D post and some small and medium-sized companies R&D post.

Chapter 2 School Recruitment Planning
2.1 Job search planning
2.1.1 Understand school recruitment
Campus recruitment is very important for both college students and graduate students. Most students find their first jobs in just a few months. However, school recruitment is only a relatively unified time, and can be subdivided into: summer internship recruitment, autumn recruitment, autumn recruitment supplementary recording, spring recruitment in the coming year, and spring recruitment supplementary recording.
Summer Internship Recruitment: The recruiting objects for summer internships are mainly junior and senior students. The time is around March to May each year. The recruitment scale is smaller than the formal school recruitment. For some students who are determined to work instead of graduate and Ph.D., they must do their best to participate in internships. Because there is a certain chance that the internship will be turned into a regular. Going ashore through an internship is easier than going ashore through an official autumn recruitment. This means that you already have a guaranteed offer before the official autumn recruitment, and the pressure during the autumn recruitment process is not so great. And your own internship experience can be written on your resume, which will add a lot to your resume. It would be even better if you have an internship experience in a major Internet company. When the interviewer sees you have an internship, they will dig deep into your internship process. (But it is not recommended to give up the official autumn recruitment because of the internship offer! Because the autumn recruitment will have better opportunities, and the company you are intern in may not all be positive)
Autumn Recruitment: Autumn Recruitment is divided into two stages: Advance Approval and Formal Approval. Among them, the early approval is generally concentrated in June-July, the official approval is generally from July to October, and the gold is nine and the silver is ten. It is described that the autumn recruitment period is September and October when the competition is the most intense, with the most job seekers and the competition. maximum.
Early approval: Early approval is mainly set up by some companies in order to grab some better and better talents faster, so early approval is generally a fight between gods (the competition is extremely fierce, and all kinds of 985 talents) , but pre-approval is very important. Because more and more companies are interested in pre-approval, many companies have already given the opportunity for secondary delivery, that is to say, if you fail the pre-approval, the official approval can still be delivered to the company again. Wouldn't it be nice to have a "Resurrection Armor". Therefore, students must participate in the pre-approval, and do not give up the pre-approval because they feel that their academic qualifications are not good or their level is not enough. However, not all companies will give you a second interview opportunity. If you are approved in advance, you will not have the opportunity to make a second delivery after the official approval. Therefore, students should pay attention to the corresponding company when submitting their resumes. Ask for good news (this is very important, so you must prepare well in advance for approval, otherwise it will affect your official approval).
Formal approval: The formal approval follows the advance approval. Generally, the formal approval will begin immediately after the advance approval is over. This is the time when the entire recruitment process has the most HCs. It is recommended to deliver as early as possible, because there are so many vacancies. After recruiting a certain number of people, they will no longer recruit. If you want to submit your resume again, it is best to submit your resume in advance, because it is very likely that even if you pass the interview successfully, there are not enough slots, which will cause the offer to fail to be approved smoothly. In addition, try to get as many offers from several companies as possible to bring better protection for yourself.
Autumn Recruitment Supplementary Record: Autumn Recruitment Supplementary Record is generally from the end of October to November each year. The main reason is that after some bosses rejected the offers in their hands due to salary or geographical reasons, some positions were not fully recruited, and these positions began to be recruited again. Generally speaking, the number of places for supplementary registration is relatively small. If you can go ashore in advance and during the autumn recruitment period, you should try your best to go ashore.
Spring recruiting for the coming year: Spring recruiting for the coming year is generally in March-May of the second year. Compared with the scale of autumn recruiting, the recruitment scale of spring recruiting is much smaller, mainly because the company did not recruit enough people during the autumn recruiting process. This is also the last school recruitment opportunity for fresh graduates to find a job.
2.1.2 Establish direction
Generally speaking, the bigger the company, the clearer the division of labor, while the smaller company requires you to be a generalist. Therefore, it is recommended that students find a larger company for their first job, improve their personal skills, and be able to gild them.
Determining the personal direction as soon as possible can save a lot of time. At present, the embedded direction mainly includes embedded application development, embedded driver development and so on. There are many directions for embedded application development, which can be biased towards the development of the QT interface of C++ or the direction of audio and video streaming media. The embedded driver development is mainly the driver development under the Linux system. The ratio of application development and driver development positions is 8:2. Various companies have embedded application development positions, and driver positions mainly exist in major chip manufacturers and large companies. There are various embedded platforms, such as RK platform, Freescale platform, HiSilicon platform, MediaTek platform, and Qualcomm platform. For application development, it is more troublesome to change the platform. For driver development, the main technology stack is at the bottom, so it is more inclined to technical experts, and it is more convenient to switch platforms.
2.1.3 Define the position
Here is a brief introduction to some positions that can be delivered in the direction of the embedded technology stack, which is convenient for everyone to refer to in the autumn recruitment process. Post embedded positions, undergraduate majors are generally automation, electrical engineering, electronic information, Internet of Things, and communication engineering. You can also transfer from other majors.
2.1.3.1 Embedded application development engineer
Embedded application development, there are many technical directions, such as audio and video development (such as driving recorders, action cameras), such as the communication industry (routers, repeaters), the Internet of Things (smart home), or you can prefer C++ to develop with QT interface.
2.1.3.2 Embedded driver engineer
The general career progression for an embedded drive engineer is that of a technologist. Driver engineers generally need to learn driver development and the Linux kernel, and the Linux kernel and drivers are not separated. Familiar with the Linux kernel can better understand the implementation principle of the underlying API, and can better write drivers, so driver engineers generally also take into account the kernel engineers.
2.1.3.2 Embedded Linux operation and maintenance engineer
Mainly perform some operation and maintenance work for the company's Linux server, with low technical content, not deep technology stack, and the average salary is not as high as the above two positions (except for the operation and maintenance of large factories).
2.1.4 Obtaining school recruitment information
I believe that there are many small partners like me who are confused about the acquisition of recruitment information of various companies, and do not know how to obtain this information, such as which companies have begun to approve in advance, which companies have begun to officially approve, and which ones can I vote for? What positions are the companies in which cities, etc.
Here are a few recommended sources of information:
1. Niuke.com, the school recruitment schedule of the Niuke school recruitment job area will list the companies that open the school recruitment schedule every day according to the time. It is recommended that friends make good use of Niuke.com and Haitou artifact.
2. Various WeChat groups and QQ groups: The school will establish an employment QQ group for each class of students and publish recruitment information. The official account of the employment office of each school will also release recruitment information every day.
3. Official website of the school. During the job search season, many companies will come to the school to give lectures, and the guides of the grade group will follow up. Remember to watch the group on time every day, and pay attention to your favorite company.
4. The official website of the enterprise. If you have a company or company you want to go to, you can go directly to their official website to find the school recruitment section, and submit your resume directly. It is recommended to fill in the internal push code.
5. Various vertical platforms will also have recruitment information.
It is recommended to use the internal push code if you can use the internal push code. There are many internal push codes to share on Niuke.com, and all major companies have them. Using the internal push code can sometimes avoid the written test, sometimes it can ensure that the resume will not be brushed, various benefits, and sometimes it can also follow up the delivery progress. The insider recommends you to join the job, and the recommender has money to take it, so employees will share their own insider code on various platforms.
At the beginning of this year, I recorded a relatively systematic introductory single-chip microcomputer tutorial. If you want, you can get it from me. It's free, and you can send me a private message. You can also get it by clicking on my avatar in black font and adding 隱重麺.
