Interview
Two rounds
First one was behavioral questions with a couple questions on projects you have done in the past.
Second round, two separate interviews, first one was technical with a manager and with the senior manager it was more a conversation. Very pleasant experience! Got the offer the next day!
I applied online. I interviewed at Discover (Austin, TX) in Mar 2021
Interview
It was a video interview, overall it was okay. The questions were medium-hard. I suggest you google: 61 Cybersecurity Job Interview Questions and Answers. That helped me as 50% of the questions were technical. PREPARE for technical questions, and have good questions at the end! If I could do this interview again I would work on that! good luck :)
