Designity Website Design interview questions

Beware of this company. They make you sign up and complete your profile on their website and schedule for a Skype interview appointment (also through their website). When the appointment time came, they were nowhere to be found. I waited for over an hour and no Skype calls. Tried contacting the person who reached out to me with the interview invitation and again, nobody answered.. Shady company. I suspect that they only sent out interview invitations so they get more people to sign up and set up a profile on their website.
