    Average Interview

    Application

    I applied through an employee referral. The process took 2+ months. I interviewed at Booz Allen Hamilton (Boston, MA) in May 2015.

    Interview

    Took me through multiple rounds of interviews. No real structure to interviews. Seemed more like a "getting to know you" session while they tried to figure out where I would best fit.

    Everyone I talked to was nice and professional. The recruiter left a lot to be desired and a very sour taste. After the last interview, the recruiter told me to expect a verbal offer within the week. After that, he went radio silent for a month. Had to follow up with a friend in another area of the company to get any kind of information.

    Application

    I applied online. The process took 4 weeks. I interviewed at Booz Allen Hamilton.

    Interview

    Two phone screens followed by an in-person interview. First phone screen was informal, chatting about your background, what your interests are, and describing the position in depth. The second phone screen went into much more depth about the role, along with more specific questions about my background. The in person interview lasted a couple of hours, and it was an in depth discussion about the data science problems I've solved and the kind of problems the Booz Allen team is looking to solve.
