I think it's obviously true that there is still a great deal of bias in hiring decisions. -I offer three personal anecdotes: 
1. The Catholic school board I worked for, for thirty years, was and is extremely nepotistic. Half of the teachers on staff at my school were former students. And this bias was displayed over multiple generations of hires, and applies in spades when it comes to those on the supply lists.
2. My wife, a small town Ontario public librarian, was flabbergasted for years at the brazen bias shown by senior librarians regarding new hires. -Resumes from men, regardless of qualifications, were swept immediately into the garbage, followed by resumes from anyone who was not Anglo-Saxon. 
3. One of my best friends, who works in IT and is fifty years old, has commented repeatedly at the ageism he has experienced in the workforce. -He was asked more than once, and right to his face, during job interviews, if he wasn't too old to be applying for a job in Information Technology.
