Recruiter knew nothing about the subject matter and asked prepared questions that were taken from the job description. Had limited frame of reference if the candidate was even qualified for the position. Suspect that the exercise was to "boil the ocean" and I question if there was even a position attached to the interview. 4 qualified collegues interviewed for same position and in each case, some objection was raised that eliminated that person from consideration. Strongly suspect the age discrimination a contributing factor.
