first + second rounds and then in person interview. They want to see how you connect your work with theirs. team is great and they are a pleasure to talk to.

The interview process spanned three months from the initial phone screen to the final round, largely due to slow and inconsistent communication from HR. Responses often took weeks, and when they did arrive, they were typically to say more time was needed to schedule the next step. The first round was a 30-minute phone interview with someone who had joined Exponent about two years prior. The second round was a virtual interview with a principal-level scientist. The final on-site round felt excessive for the position. It lasted seven hours and included: A one-hour technical presentation with Q&A; Individual meetings with seven interviewers; A lunch session. Most interviewers were professional and well-prepared. Senior staff in particular asked thoughtful, well-structured questions and provided sufficient context. However, two interviewers, both relatively new, stood out for the wrong reasons. One seemed to attempt a McKinsey case-interview style question without proper setup, leaving it confusing and irrelevant to the role. Another focused the entire session on a topic I had already disclosed was outside my expertise, showing no interest in exploring other areas of my skills or knowledge. Overall, while some parts of the process were fair and constructive, the length, HR delays, and unprofessional behavior from certain interviewers made the experience unnecessarily frustrating.
