Had an interview today and they barely asked me any questions. Is that a good or bad thing?

Agreed, I've had a few experiences like this and it always meant a) I essentially already had the job and b) one or more aspects of the job was a complete cluster f**

either they already picked someone else and are going through the motions or they picked you…

When interviews go like that, I assume that I was the first persons application they grabbed and just rolled with it. My experience at these jobs then consisted of managers who didn’t give a shit about me or my personal life. For example I took a part time position at one, and they scheduled me damn near 40 hours a week despite me saying explicitly I’m only looking for part time. The turnover for these positions also seems to be very bad as well. This may not be the case for you tho and maybe my experiences were just bad

Some times interviewers ask very casual questions so don't worry about it. They will provide u a good feedback. For what profile u interviewed ?
