Blissfully interview questions

The interaction leading up to the call was too casual to be considered professional, which was also continued during the call session. For example, they did not bother to send a scheduled invite for the interview to which I had to do, and proudly admitted, " I didn't even think of sending an invite." Are you serious? They did not seem to have little to no grasp of the culture that they already have in place or are attempting to cultivate. As they simply reiterated what their product was. Again....are you serious? When asked what the list of responsibilities for the role, they reached out to me would entail. They stated that they did not know in full. Again........ARE YOU SERIOUS? Please do not allow them to waste your time with any "opportunities" they may have available. Very unorganized.
