I recently joined the Propeller team following a four-stage interview process over approximately six weeks. The stages are fairly standard and they're clear from the outset what's going to happen - a phone screen to get a general sense of your background, two face-to-face meetings with mini-cases during each one, and a final business case presentation at the office HQ with one of the founders present. Propeller consultants lead every stage of the interview, so you get a real sense of people you'll be working with, as opposed to a more traditional, centralized HR interviewing process. For me it was an important factor to engage early-on with a group of smart and personable colleagues, and it helped me feel confident that there was a good cultural fit w the company. The business case presentation is certainly nerve-wracking at the beginning, but it actually turned out to be an interesting scenario that gives you a chance to demonstrate first-hand your skills and experience. Overall the entire experience was very positive, and I was thrilled to receive and accept an offer.
