Composite Apps Full Stack Developer interview questions

I applied online and was interviewed onsite at Irvine office Los Angeles. There are 2 onsite interviews 1st Onsite. The person speaks for about 1 hour telling about history of company and then technical developer joins the interview where he assigns you a web project and promise you to give job if you complete his project within a week. (SCAM Nothing like this really happens I completed the project in less then one week with extra credit section which was mentioned in question) 2nd Onsite: A small demo about your project with minimum of 5 slides. According to the promise made by technical developer a candidate would except offer letter or some technical question on project but they say we will get back to you and no ones get back to you. When you try to follow up no one replies. Total waste of time. If you have interview at this company think twice before moving ahead
