Began through on-campus interview. 2 on 1 interview, 2 coding questions over 1 hour. Questions were straightforward and focused on problem-solving and communication, with direction from interviewers when asked. I passed the first round and they asked if I was available to stay for a second. Upon saying no (I had class right after) they offered to fly me to NYC. In NYC, I went through 2 additional 1 hr technical rounds, with questions increasing in difficulty. Questions ranged from the design of distributed system to implementing and applying an LRU cache. After this, an HR representative chatted with me for 20 minutes. Finally, a manager came in for 30 minutes and asked me a final technical question. I received an offer 6 days later.
