I was reached out by a recruiter who called up to ask if I would be interested in a position that would be a good fit for me, given that she'd seen my resume in their system. I obliged and thanked her for reaching out. A couple of days later the hiring manager reached out of the blue and asked if I was free to answer a couple of basic questions. I unfortunately had another interview lined up in a couple of minutes, and had to ask him if it was okay for him to reach out in an hour and a half. He was very nice, and graciously accepted to do so. He later called me an hour and a half later, and even asked if I did well on the other interview, which I thought was nice of him. I answered basic security related questions such as Citizenship/Bankruptcy/Drug Abuse questions. The position requires a Security clearance, and that is probably why they started out with that. Later the questions turned towards my background and how my prior work experiences were/weren't related to the job description in question. After answering in ways to make them seem similar, he seemed convinced that I would be a good fit for the role. I was given the time to ask him some basic questions as well. At the end of the interview he said I should hear back from them soon. A couple of days later I was emailed another security questionnaire to fill up. And a week after that I was invited to a hiring event. They flew me out, put me up in a nice hotel, and had me attend their one hour interview the next day. This interview round consisted of three interviewers who were the head of a mega team, the head of the relevant team, and the hiring manager for the job in question. The questions were all STAR related, but were laced with technical interludes to see how well you would link your experiences to the job description in question. A pro tip would be to make sure you answer in such a way that you relate to some point or the other asked in the job description! Didn't hear back from them after the interview happened. I had a competing offer from another similar (plane) company 2 weeks later, and I reached out to them for an update. Later I got an email from them saying the hiring team had decided to move forward with another candidate. Wanted this offer mainly to have negotiating leverage with my other company, but wouldn't have taken it up if I'd received it.

Easy interview, few technical questions mostly behavioral. They were mostly interested in the potential and the interest of the candidate. Study the company and the group that you are applying to.
