Before you take a call, make sure they have done their homework and are presenting a role that is the right fit for you. If they won’t tell you the company or basic information through email, throw them out — they’re not acting in good faith. On the call, cut right to the chase and ask for salary range and what the role will actually entail. They should tell you. Make sure they have a specific hiring manager in mine. A targeted role will be more promising than a general one.
