Email from Hiring manager for my resume submitted 2 years back. When I showed interest a recruiter contacted me and arranged Phone interview with hiring manager. Followed by in-person interview (4 round, 1hr each)

Had a phone interview with the hiring manager. Went over the job requirements and day to day duties, and my reason for wanting to leave my current job. Then had a one on one interview with the manager and two engineers. Quizzed me on the job requirements, etc. Gave back
