TA reached out to me via LinkedIn. Had a 30min screen the following day, and then scheduled me for a 1.5 hr interview the following week. First part was typical interview but very casual/conversational. 2nd part was the coding portion. The technical portion was a java coding exercise with a pair programming aspect and focused on REST API and design pattern knowledge, few deeper technical questions along the way and they even allowed me to google for certain parts of finding the solution. Not 2 days after I was called for the offer. All the interviewers were super friendly and helpful. The entire process from initial message to offer did not take more than 2 weeks; incredibly efficient. Honestly one of, if not the best interview experience I've ever had.
