TD Cybersecurity Internship interview questions

Interview was 30minutes. The interviewer was amazing! They were super kind. We went over my resume and my experiences - it was more like a conversation for me than a formal Q/A. After the interview - within like few hours (same day) I got a call from "No Caller ID". I usually don't pick them up but I did that day anyway and it was from TD and they were offering me the position. I was kinda surprised because i was like "Just like that? I had interview few hours ago" so i confirmed with the person who called and it was true and they said " we like to surprise people" or something like that. Well of course i was super happy and yeah then it was background check and I am still in process.
