The difference between joining years ago and after.

The difference between these two time periods lies in the number of posts, the scale of competition and the training period.

1. Number of jobs: fewer jobs were recruited before the year, and more jobs were recruited after the year.

2. Competition: before the year, there was little competition, and there were many job choices. After the year, there was great competition, and there were few job choices.

3. Training cycle: the induction training cycle is short years ago and long years later.
