I was reached out by a recruiter on LinkedIn, followed by a call with the hiring manager. The hiring manager outlined the job and its responsibilities and asked me about my experience. This was an informal call and not an interview call. I was scheduled for three interviews the following week. First one with another person on the larger team, second with the hiring manager and the last one with the hiring manager's manager. In my first call the interviewer seemed very uninterested- kept yawning and stretching which made me also uninterested in the process and threw me off my game. the other two calls were comparatively better but by this time I had already given up.
