First, will ask you to join without pay for 3 months. If you don't agree then they will think of paying you.
Read their offer letter carefully if you get proper offer letter on time.
They will say they will make you join as an employee but if you are experienced. They will make if join as contract worker. So, that they can fire you anytime.
And rest other good reviews they have asked their own employee to put good reviews about them on glassdoor.
I thought to share it to all of you . And please don't join because you don't have any job . It's a big scam
