Initial contacts come from HR, with their initial screening. These contacts don't always have a good sense of job duties, so its good to focus on the generic "I meet requirements" piece first, then try to impress afterwards if possible. Hiring manager will likely reach out to a handful of individuals afterwards, interviews are usually scheduled to happen with not only the hiring leader, but with also people on the team and/or colleagues the position will interact with. The interview process is largely left up to the hiring managers' discretion at the Manager/Director/VP levels. Lower level positions (analysts, customer service) are likely to have more structured interview processes. Pay close attention to the questions, as these are usually created by the interviewer themselves, and will key you in to what they are looking for and what they value in an employee.

Interviewed with 6 directors and VP's for Chief of Staff role in Risk team. Interview occurred all in one day, but took about two weeks to coordinate the date. After the interview process, I was required to take a drug test and complete background investigation. Overall, I was a little surprised how easy the interview process was, but I guess compared to investment banking most interviews are a walk in the park. There were not many technical questions.
