interview
After ten years of programming experience, how can technical interviews improve performance?
It is another year of "three gold and four silver". Unlike the past, the current workplace environment is no longer the beautiful era of two-way travel.
There are more job seekers, fewer HCs and higher job requirements. In the face of such difficulties, how should technicians break through?
Tencent Cloud Developer Community specially invited former Shell Financial Services small and micro enterprise ecological CTO, Tencent Cloud TVP, and Mr. Shi Haifeng, who has many years of technical management experience, to share the twists and turns in the technical interview, analyze the problems behind the low passing rate of engineers in the interview, and propose 10 strategies to improve interview performance, hoping to help everyone,

Play EdgeOne
Tencent EdgeOne product evaluation experience - not only acceleration, but also a solid shield for your digital security!
The Edge Security Acceleration Platform EO (Tencent cloud EdgeOne, hereinafter referred to as EdgeOne) launched by Tencent Cloud is a solution based on Tencent's edge computing nodes to provide acceleration and security.
That is, the traditional CDN network distribution node is targeted, but it has more powerful advantages in acceleration and security protection. In addition, EdgeOne also provides edge functions, four layer proxy, DNS resolution and other capabilities.
EdgeOne's richer functions, more flexible configuration and easier way to get started are totally better choices than CDN products!
