I interviewed for a position in San Diego. I arrived 15 minutes prior to the recommended arrival time. The interviews were conducted at another building, so I decided to take the shuttle, which made me late.

I met with the director, who asked me some logic questions, which I probably didn't fare too well on.

Then, I went to two other one-on-one technical interviews, where I was asked about past experience and how I would approach certain problems, specifically regarding troubleshooting.

This was followed by a lunch interview and, finally, an HR interview.

The process itself was very streamlined. I guess I didn't do too well, since I did not receive an offer.

There is a body of water that starts with 1 square unit and doubles in size every day (2 units after 2 days, 4 units after 4 days).

It takes 100 days to fill up.

How many days would it take to fill if you started with 2 square units?
