Of course it's illegal. First of all, it is the company's obligation to provide training, not the employees' obligation. During the training period, you must be paid. Secondly, company layoffs are not arbitrary layoffs. Employees who do not meet the requirements of the Human Resources and Social Security Bureau shall be compensated.

Besides, this is the job of selling houses. If you want to find a consultant to recruit candidates, this kind of work can be done by individuals.

To sum up, this company is rubbish, so don't go.
