I am recent graduate student, having just secured a good position in a financial services firm that I love. I happened to hear from a company that found my resume online and want me to come in for an interview. As I am currently employed, I declined. What struck me was the tone of the company recruiter, particularly its informality. The financial services sector has always been characterized by professionalism and tradition and strict adherence to procedure is prized from what I experienced. Interviews are designed to be formal / procedural, with the aim to strictly assess the qualifications of the candidate with deviation from basic business being frowned upon. This was a Fortune 100 company. From the tone of the recruiter, it seemed an informational interview was been requested, in line with a question - answer session. Are such informal, informational interviews the norm in the financial services industry?
What appears professional and procedural on the surface of the actual business, isn't what happens in all of the other departments that are really not part of the financial business part of the company. HR is one of them.
Maybe when they recruit college grads they can follow all the nice protocols because they know all the students are looking for jobs and some universities may have over-site on the process, but this recruiter is trying to poach you from another firm. They're probably a little more sneaky about it. They'll try to get you to put your guard down by telling you there's no reason to follow the rules. It's dog eat eat dog.
Unfortunately, they're rewarded for hiring people and they will be willing to be a little less professional if they feel it is necessary.
