I think when he says 'white board interview', he means 'algorithms and data structures screen, which may or may not be on a whiteboard'. So, for instance, you could give a data science applicant a dataset and pandas and tell them to make you a report 'about sales projections' then see what they come back with. Or you could ask them to sort a list of strings in log(n) time and n space using a recursive solution. The first test would probably benifit an experieced applicant because hopefully they will have a better understanding of what buisness actually needs. The second test would benifit a recent graduate, because they will have done algorithms 101 more recently and remember a canned solution. Of course, experienced applicants will revise this sort of problem and play on hacker rank for a couple months before a job hunt, so it will also benifit candidates who are actively job hunting, rather than applying for a specific oppertunity
