I would like to ask, why can't we recruit people for it companies that sell and implement software now?

There are multiple reasons for not hiring.

1, the most direct reason for not recruiting people is that wages and benefits can't be given, which is the fundamental reason.

2, can not keep people, is the working environment atmosphere and culture is not in place.

3. The resignation of old employees means that the promotion space is limited and long-term development cannot be achieved.
