It wasn’t a bad interview, but they were not transparent about much. They painted the picture of the place in a whole other light. Ask to see a job description with your expected duties listed before the interview, if you can’t get that then be sure to ask if you expected to vacuum and clean the bathroom as well. If you do not want a office job that expects you to clean, even if it’s not in your scope of work on your job description than you will be fired the moment you say you aren’t doing that.
