April is almost over, which means that the golden three silver four will be finished. I don’t know if you find this year’s interview harder than before; Last year, due to the epidemic, programmers were reluctant to jump ship, and now the IT industry is becoming more and more serious. This year, the recruitment market is very difficult.

Recently, many friends in the group are asking, how to seize the tail of silver Four, impact outstanding Internet companies; In fact, there is only one way, to systematically upgrade their own technology stack, quickly make up for their shortcomings, otherwise even if entered the excellent company is easy to be involved in. Can comprehensively improve their technical level, a short time is not to do, can do only surprise interview, short time to achieve their ability to build rockets;

The day before yesterday, when I was visiting Github in the back garden, I accidentally found a copy of “Ali April Java question bank and answers (technology + personnel)”, but I could not find it any more after only one night, is it blocked? Fortunately, I have a habit of downloading directly to my computer, and I will share it with you today.
