The 2020 average salary figures are out.
Under the impact of the epidemic, the growth rate of average wages has dropped to a low level for many years, but it still maintains growth.
Among them, the average salary of urban non-private units exceeds 97,000 yuan; programmers are still the most popular, and the average annual salary of the IT industry exceeds 170,000 yuan.
97,379 yuan for non-private units, 57,727 yuan for private units
The data shows that in 2020, the average annual salary of employees employed in urban non-private units across the country will be 97,379 yuan, an increase of 7.6% over the previous year, a decrease of 2.2 percentage points from the previous year, and an actual increase of 5.2% after deducting price factors.
In addition, the average annual salary of employees in urban private units was 57,727 yuan, an increase of 7.7% over the previous year, a decrease of 0.4 percentage points from the previous year, and an actual increase of 5.3% after deducting price factors.
Urban non-private units specifically include state-owned units, urban collective units, joint ventures, joint-stock units, foreign investment, Hong Kong, Macao and Taiwan investment and other units. Urban private units specifically include private limited liability companies, private joint stock companies, private partnerships and private sole proprietorships.
Average wage growth slows down but keeps growing
The data shows that the growth rate of average wages of employees in urban non-private units is the lowest point since 1984, and the growth rate of average wages of employees in urban private units has dropped to the second lowest point since statistics began in 2009.
Meng Canwen, deputy director of the Population and Employment Statistics Department of the National Bureau of Statistics, said that under the impact of the epidemic, the average annual salary of employees in urban units still maintained growth, reflecting the great achievements made by the Party Central Committee and the State Council in coordinating epidemic prevention and control and economic and social development.
After the outbreak of the epidemic last year, the Party Central Committee and the State Council coordinated the prevention and control of the epidemic and economic and social development, and introduced a series of measures to reduce taxes and fees, and assist enterprises to stabilize jobs. While promoting the stable recovery of the economy, they effectively reduced the operating costs of enterprises and promoted It has improved the efficiency of enterprises and created conditions for wage growth.
Programmers are so fragrant! The IT industry has the highest average annual salary of more than 170,000 yuan
In terms of different industries, the IT industry has the highest annual average salary among urban non-private units and private units.
The data shows that among urban non-private units, the three industries with the highest annual average wages are information transmission, software and information technology services at 177,544 yuan, scientific research and technical services at 139,851 yuan, and financial services at 133,390 yuan.
Among the urban private units, the three industries with the highest annual average wages are information transmission, software and information technology service industry with 101,281 yuan, financial industry with 82,930 yuan, and scientific research and technical service industry with 72,233 yuan.
The salaries of programmers have also maintained rapid growth. Among urban non-private units, average wages in the information transmission, software and information technology service industries will increase by 10.0% in 2020, an increase of 0.7 percentage points over the previous year, and the growth rate ranks third. Among private units, the average salary growth rate of information transmission, software and information technology service industry was the highest, reaching 18.7%.
Why are programmers' salaries increasing so fast? According to the analysis, under the influence of the epidemic, new consumer demand such as online office, online education and remote consultation continued to be strong, driving the average salary of the Internet and related service industries to grow rapidly.

Algorithm and data structure chapter
For the client, the major manufacturers basically will not have too difficult questions, the difficulty is basically at the middle level of "Sword Finger Offer" and LeetCode, and basically all of them can achieve handwritten bug free. For complex implementations, the interviewer will also give hints or just let you talk about some ideas. Except for Baidu, everything else needs to be written by hand. Because Baidu does not need to write by hand and examine ideas, it will be more difficult in terms of difficulty.
