Twice I have replied to vague job listings of this company through Craigslist asking for more information about the company and position. I did not include a resume, but asked many questions. Both times, I received some sort of automatic scripted response inviting me to an interview signed by an administrative assistant from their company.
The first time they thanked me for sending them my information. I did not send any information, and they didn't answer my questions. They just invited me to have an interview for a position that I knew nothing about.
The second time, they sent an e-mail that said "Good morning" at 3:00 pm in the afternoon. Again, I didn't send any information, and they invited me to an interview. I had asked if it was a telemarketing or sales position, as well if they could tell me about the company, and other various questions. They again did not answer my questions, except for telling me the name of the company was "Fratelli" in the Teleking Group building though it is really Omega Auto Glass. I had checked up on the address and suite number and found that it was Omega Auto Glass.
I believe that if a company is an honest company, they can tell about what position that they are actually hiring for in the listing, and if they don't have all the details there, they can inform applicants in the response prior to inviting the applicant to the interview. They won't need to be misleading. I also believe that if it is a professional company, they will screen applicants before inviting them to an interview unless they are having a job fair.
