The interview process began with screening calls from the recruiter and hiring manager, followed by three technical interviews with various lead/senior engineers.

Next, there was a technical presentation and an on-site interview.

The wait time between interviews ranged from a couple of days to a week and a half.

Overall, the interviews were quite interesting, and the entire process was actually rather enjoyable, until the rejection.

You're sitting in a canoe inside an above-ground pool, holding a bowling ball. You drop the bowling ball. What happens to the water level of the pool?

Lots of questions arose on previous projects.

Some questions were on basic engineering (i.e., cantilever beam, hoop stress, effects of thermal loads, etc.).
