Current epidemic situation , Many of my colleagues and friends work at home , Some small factories are facing layoffs because they can't hold on , At the beginning of this epidemic, I left my job and interviewed many large front-line factories , Now many companies have also sent admission letters .

So when people are trapped at home because of the epidemic and are busy hoarding vegetables tomorrow , But I have a pile of it in my hand offer
, I don't know whether to cry or laugh ... There's a good saying : There is a happy worry called choice offer,Offer Many also worry about choice , People with difficult choices are even more headache .

The epidemic will eventually pass , But it will be a little late if we wait until then , Just take advantage of this time, when you are at home, you can learn your skills and interview skills
, When the epidemic situation eases, you can choose to change jobs to your favorite company . Today I'd like to share with you a set of Ali I used to watch during my interview P8 Organized by the boss 2022Java Advanced learning route + Collection of high frequency interview questions ,
I hope everyone can get their favorite after the epidemic offer.
