Interview Process
The interview process began with a technical phone screen. The interviewer asked about my work history, what motivates me, and what I find interesting in my projects. I was also asked about the most queries per second (QPS) I had experienced on a project and to describe my tech stack and day-to-day work. Although the recruiter indicated that I should use Java, the interviewer allowed the use of any programming language, so I opted for Java.
