Got referred by a friend working for pinterest for a security lead role. The job description was very vague with no clear description by the recruiter. Got called in for an onsite interview day after a brief phone interview. Since it was a new role and area (nobody who interviewed was really a security expert), the interview was more conversational (strategy and culture fit) than anything technical. The hiring manager only spent 5 minutes. After 2 days the recruiter came back and said while they liked my background and skills, they have decided not to hire anybody for that role. No feedback, (good or bad) or explanation on what they want.
