As an IT practitioner, no matter whether you have plans to change jobs or not. Participating in some targeted recruitment interviews from time to time is also beneficial to individuals.
On the one hand, it is possible to understand what are the hotly recruited positions in major factories. These hotly recruited positions can often indicate the enthusiasm for the development of related industries in the society and the direction of capital investment.
That means more opportunities. On the other hand, in the process of interacting with the interviewer, you can also learn about the technical architecture of some major manufacturers, related technology stacks,
Seeing the leopard in the tube is beneficial to broaden one's horizons.
Most directly, participating in the technical written test/interview is equivalent to giving yourself a chance to catch up for the test, which is a test of your technical ability, even if your ability cannot meet the requirements of the interview position,
You can also go home and review the game, check for gaps and make up for omissions, and find the direction of learning and hard work. This is very important, because many people are prone to slack in the daily work of screwing screws and reinventing wheels.
Even the psychology of blind self-confidence.
Later, I will share some of the technical interviews I have participated in on the official account based on my memories, and I will also do some analysis of the interview questions when the follow-up time permits.
