Had five 45-minute interviews back-to-back with 15-minute breaks in between.

The interviewers talk to each other while you are taking a break before the next one comes to get you.

This was a mix of personality/behavioral and "What would you do in this scenario..." questions.

The interviewers were laid back; dress was casual. You can act like you're having a normal conversation while also writing code on a whiteboard.

Question about data encryption over HTTPS websites. He drilled really deep, asking questions like how secret and private keys work, how the secret key is shared, and how encryption of data actually takes place on websites.
