ET Solar interview questions

The HR contacted you through your phone number and said we have reviewed your resume. Then, he gave a list of jobs and let me pick a job. What is the point of we have reviewed your resume? I feel this is a fake company. The interview is pretty easy and I got the offer within seconds after finishing the online interview through Google hangouts. The interviewer's profile photo is like a screenshot. No questions can be asked or answered through this interview. The next day they sent me an offer through email. The domain name from the sender is from gmail.com. If this is real then it should send from et solar. Also, the employment form has no company's information at all. I think they just try to get your SSN at this time. I stopped the process.
