This was the initial phone screen, which took an hour. It started with an introduction by the interviewer, followed by a coding session that occupied the majority of the time. In the end, I had the opportunity to ask the interviewers questions about the company.

The question was sort of like a design question, but it required me to define the input and the output the way I wanted.

After that, it was a session of writing code and tests for the code.

There was also a follow-up question that didn't require me to code, but I wrote it anyway.

In the end, I got to ask questions to the interviewers.
