The interview process involved:

• One phone interview
• An afternoon of 1:1 interviews on site
• Another day of 4 1:1 interviews
• A final phone negotiation with HR

First technical interviews were very standard and focused on my background. They included a group interview and an impromptu presentation. Questions focused on Java programming and general algorithm analysis, as well as one or two "brain teaser"/problem-solving questions.

Second interviews were more geared towards fit and focused on goals, interests, and provided an opportunity for me to ask questions.

Two people are each stuck on their own island, connected by a ferryman with a lockable box.

Each person has their own lock and key, but can't send the key along with the box.

One person wants to send the other a diamond, but it must be placed into the box and locked, or it will be stolen by the ferryman.

How do you send the diamond without the ferryman stealing it?
