Why does ByteDance always recruit people?

Not only in ByteDance, but also in every large and medium-sized Internet company.

In internet companies, the front-end staffing is relatively large, especially for large and medium-sized companies and smaller companies. The overall technical team can reach more than 50 people. At the same time, large companies have high requirements on the ability of technicians, and there will also be a elimination system, so we can see that they have been recruiting people.
