The interview process was very efficient. After solving the HackerRank challenge, it took about a day to get a call from the recruiter and set up a follow-up coding interview. After only a few days, I got to the onsite, which consisted of a system design interview, a coding interview, and two behavioral interviews. All the interviews were enjoyable, and the questions were well-designed and understandable. The coding questions were not too difficult, and there was an emphasis on providing a testable solution. Each time, the interviewer would ask me how I would test my code and what I would improve.

Given a list of entries of type { "from": User, "to": User, "message": Text }, create a leaderboard of users who received the most number of messages.

Follow-up: Add a way of filtering SPAM messages (multiple messages from one user to another of the same text).

Given a list of businesses and a desired search text, find the first 5 businesses prefix-matching the searched phrase (on any of the words).
