Are you actually interviewing the company while they interview you?
A lot of sites and recruiters like to say things like, "interviews are for both parties" and "it's a two-way street" but I've never talked to a candidate who actually believed this. Usually candidates are trying to impress us and we have all the leverage since we have the offer they want.
Very rarely have I seen a candidate interview the company. The only time I have heard of this is for executive roles, cxo. A position where there wasn't over 100 applicants waiting for a shot.
For everyone else, how are you ensuring the company is a fit for you? Do you even care if you're another worker bee?
