There were four 45-minute interviews with four different interviewers. Two focused on basic algorithms, one on app design, and one was behavioral.

I had practiced coding for several weeks, but the "number of islands" question got the best of me.

The interviewers were very easy to talk to and professional. They seemed to be trying to be helpful, but as it was the first interview, I must have gotten too nervous.

The behavioral interview was easier since it focused on my previous experiences.

Although things didn't go as well as I had hoped, I learned a lot from the experience.

Given a two-dimensional array of '1's and '0's, determine the number of connected islands.
