It's too embarrassing for me, Ali has 7 rounds of interviews...

foreword

The general environment this year is very bad, and the layoffs of Internet companies are more serious than in previous years, but this year is just the time when my first "five-year plan" ends, so I can't delay it, so I prepared early to change jobs It also started after the epidemic situation improved.
