Magna International interview questions

This was the strangest process I’ve ever been a part of. I was reached out to by a recruiter that saw my resume on a job board and asked to fill out a “self interview” which took about 30 minutes to complete online. I then received a canned email with a salutation of Mr/Miss/Ms/Mrs requesting a phone or email interview and giving me one date and time. I received the phone call and the lady was very straightforward: “this is an interview, do you understand?”, “keep your answers brief as we don’t have much time.” She proceeded to ask me 3-4 questions and after 9 minutes she offered me the job. I received an offer letter via email later that day with no information about what division of Magna I would be working for, who the team is, any benefits information. So I responded with these questions and was ghosted. THIS WAS THE STRANGEST PROCESS OF MY LIFE. I came in here to see if this is happening to anyone else, because if this is how they are trying to get employees - good luck!
