Analog Devices interview questions

There was a screening interview with the manager, and then a technical interview with the manager and an engineer on the team, the screening interview was just to see background, and the technical interview contained analyzing C code for mistakes, a very simple algorithm, analyzing logic diagrams for their output, and writing truth tables, there was also a question on the transfer function of a analogue circuit

Recruiter reached out to me on LinkedIn - phone screen was good, recruiter gave me a good understanding about the position. - then ghosted me for 4 weeks - recruiter reached out again to schedule a Zoom interview with hiring manager - got feedback next day to interview with head of department - then ghosted me again, it’s been 4 weeks It seems like if they need something from you they chase you down without giving you reasonable time. When they don’t need you they just ghosted you, never heard back. It would be nice to at least reply email and give Candidates update on status. It is frustrating to experience this kind of interview.
