First stage (HackerRank): Quite an interesting and logical problem related to their product. It was about average medium-level LeetCode difficulty, but you either had to have solved it before or know the algorithm to get to the solution quickly. Second stage: You’ll get a letter from HR saying the stage will be about iOS coding. Don’t waste your time preparing iOS-specific stuff — it’s actually just live coding of an average LeetCode easy/medium problem. I liked the interviewer—a very friendly and intelligent person. I didn’t pass, but solely because I wasn’t attentive enough that day. Good luck, and don’t forget about the normal distribution.

This interview process consists of four stages: an HR phone screening, a HackerRank assessment, an online live coding interview, and an on-site interview. The HackerRank round gives me 60 minutes to solve a medium-level LeetCode-style problem related to handling network requests in a real-world scenario that could appear in their user stories. The online live coding interview is a 50-minute session focused on a string manipulation problem. Unfortunately, I wasn’t able to pass all the test cases or finish the solution in time, so I didn’t move forward in this round. I’m not sure what the next steps would have been after this stage. They also asked to record the interview, and the interviewers were quite friendly.
