1. Request to have some date of birth, graduation date etc on the CV. It's by no means fool proof, but it at least prevents a 23 year old passing a person with 10 years of work experience.
2. Replace phone interviews with Skype interviews. She says many times they can actually see the candidates googling for answers and reading the top most result. Of course, they never hire such a candidate.
3. Maintain a company-wide data-base of who is hired/interviewed from which consultancy and if the there were any red flags. This will help other groups in a big company. Since there is a written record, people also tend not to interview from the same bad company again and again and wasting everyone's time.
Then, they tell you that they will provide you with 2-4 week training which allows you to lie on your resume and put down 5-7 years of fake experience. Their account managers send you job postings and ask you to create fake resumes that are specific to each posting and they have in-house people who proxy your phone interviews.
Really bad, but I think more and more people are catching onto it.
