i had my interview today and was asked the same question. also similarly, the interviewer had no sense of humor. it was not a enjoyable experience because i think i gave like 3-4 different ways of making a cantilever, but i was asked "what else?" like 10 times for the cantilever problem alone. i also have 7 years of work experience, but there was 0 question asked about it.

The interview went well overall. The interviewer opened with a discussion about a project I'm proud of, then a beam scenario question that covered structural and load analysis, stress and deflection, and material selection — testing my ability to connect first-principles thinking across the full problem space.

Interview with hiring manager then virtual onsite. They ask you general mechanical engineering questions as well as questions dependent on type of team and skills they are looking for. Not bad overall just brush up on basic beam deflection, GD&T, Design analysis etc.
