2-3 weeks after applying online, I received an email from a recruiter. They mentioned I had worked with another recruiter there previously and wanted to schedule a phone call. However, I had never worked with or contacted anyone at Reddit before.

1. Recruiter phone call: They asked: "Why Reddit? What's your favorite subreddit?" They explained the next step was a 1-hour technical interview via video and CodeSignal. They stated it would NOT be an algorithm LeetCode CS-style interview.

2. Technical video interview: They asked 3 tech trivia open-ended questions for the first half. Then, the next 30 minutes involved a medium-hard level LeetCode algorithm problem, which was exactly what the recruiter said the interview would NOT be.
