The recruiters who emailed me were very nice and helpful. I was scheduled for two phone interviews, but unfortunately, I did not make it past that stage. The recruiter does send a PowerPoint with things to know for your interview (deadlocks, livelocks, context switching, etc.). However, the phone interviews are so short that your interviewer will likely not have time to ask you about those topics.

Make sure you know your resume inside-out, in case your interviewer asks you to implement something you used in your past projects (e.g., multithreading a matrix problem). Also, focus on solving problems in Cracking the Coding Interview (CTCI).

This seems like trivial advice, but I made the mistake of focusing exclusively on that PowerPoint and not on more fundamental concepts.

First Interview:

Name a difficult bug that you had to solve in your past projects.

Implement Conway's Game of Life (using a method that receives a 2D array as input).

Second Interview:

Tell me about yourself.

Create a method that determines if a 2D array is a Toeplitz matrix.
