Having spent the last 20 years either running Executive Recruiting at large FS firms or working with leaders of these firms as a headhunter, I have seen any number of "interview technique" suggestions. But as this HBR article shows, with the advent of the knowledge economy and reams of information available to candidates, clients needs to be smarter about face to face interviews to get the most out of them. And should not forget to sell the role and the company too!
Some of the long-held ideas about how to conduct interviews are no longer accurate. For example, there’s no such thing as a surprise interview question anymore. With sites like Glassdoor.com, candidates can identify each of your likely interview questions and expected answers ahead of time. With that information, candidates now routinely prepare and video their practice interviews to the point where their responses are universally impressive, if not genuine or accurate.
