A friend referred me to Yahoo!. The hiring manager then reached out regarding an opening on a team that sounded really interesting. Instead of the usual telephone chat, I decided to walk into Yahoo HQ. We had an hour-long conversation/interview, where we primarily spoke about issues one would face writing software on Linux platforms – OOM killer, cgroups, and /proc. I felt this was one of the best conversations.

After this, I was called onsite. For Yahoo!, this process moved pretty quickly. The hiring manager made a very sincere effort to hasten the onsite process. I met with three people for my onsite.

Onsite 1

• In a client/server scenario, serialize/de-serialize a balanced binary tree to be sent from the client to the server.
• Linux system programming fundamentals, including the /proc filesystem and OOM killer.

Onsite 2

• Linux system fundamentals, with more /proc filesystem-based questions.
• Structure of a binary (assuming ELF) on Linux.
• Programmatically print the offset of a member inside a variable of struct type.
• Virtual memory fundamentals.

Onsite 3

• Given a binary min heap, insert a new member.
