Tech Mahindra — fake job offer received

A job was posted for Tech Mahindra for a Graphic Designer position on LinkedIn. I applied and got an email later saying that I was scheduled for an interview at 8am the following Thursday, Aug. 16, 2018. It was scheduled to take place through Google Hangout. When I signed in, the person wouldn't talk to me through the video option, only instant messaging. The email address they used was: [protected]@gmail.com After the interview, they said I had to wait for an hour for them to talk to someone and come back. They said it was a work from home job. After they left, I did more research and found it was a job scam.
