It took about 2 months to initially hear back on my application; however, once the process started with the initial recruiter call, it progressed very quickly. The interviews felt very fair and balanced, and everyone wanted to ensure that the position would be a great fit in every respect (technically, culturally, etc.). Everyone was extremely kind and respectful throughout the entire process, and I left with a great impression of the company despite not being selected.

Specific and thorough questions regarding DNS, cryptography, deployment, reliability, and resiliency in distributed systems. You really want to prepare ahead of time and understand these areas very well.
