Is such a cultural communication company deceptive?

There are many such companies out there, which must be deceptive. Those who stay will not get money in the future. They met similar ones when they applied for jobs before. No matter what position you apply for, the premise is to send him flyers outside for ten days. Listen, it's a lie. No matter who they apply for, is it true? Can't even think about it? You worked for him for a month, too. If you found someone else's job a month ago, it might be easier than this. Why waste time and energy in that company?
