Phone screen, then onsite.

I have had two interviews with Google, and both were awful experiences.

This time, while scheduling my onsite, I was told that as a new mom, I should just wait a year before applying again because I wouldn't be able to prep. Basically, they don't want new mothers to apply to Google.

I attempted to get my recruiter's manager's information, but they wouldn't give it to me.

I am a senior hire at this point, and they waived the phone interview because I am so qualified.

After these experiences, I would not go to work for them and wouldn't recommend others to do so either.

How would you design a system for a robot to learn the layout of a room optimally and traverse it completely?
