Arranged via a quick call with the HR and then went to the technical interview. I was interviewed by 3 principal engineers and 1 senior staff engineer in 2 separate sessions, Most questions tie back to school fundamental such as creating Free body diagram, what is the glass transition point of a material that I mentioned about, deriving the velocity based on a spring system with a weight on it.

I feel that the interview emphasize alot on fundamental or even textbook knowledge where most of I failed to see what will be the actual scope in the company that require me to have these answer on the spot without any reference

1 month pass and I still haven't gotten any feedback and reply on my interview outcome

What are some of your work experience in product development?

Could you draw the free body diagram of a door hinge?

What is the glass transition temperature of the nylon material?

Derive the formula for a spring under load, and what will be the acceleration of the mass if it is disturbed?

Tighten your talk about your past experience in product development.
