I had 2 rounds of interviews. One with the hiring manager and other with a technical team. The approach was professional and mock questions were framed around the Responsibilities defined in the job description. There were no asks on flexibility to pick up other functions on ad hoc basis. Working at the same company now. Job is inline with the interview and job description provided.

Unprepared- asked questions not pertaining to job. Age was a factor. Did not read resume prior to interview. Asked If I had a problem working 60 hours per week and weekends. Questions pertaining how I would address a client in a unfortunate situation- how I would spin the answer.
