Whole process took about 1.5 month. There are 3 stages: hackerrank tasks, behavioral interview and online interview (I had 2 online interviews with 2 different teams). First two stages are very easy, 2 easy algorithmic questions on hackerrank and later on some behavioral tasks. But I have mixed feelings about the last part which is the online interview, the first online interview was chaotic, they were screening me for so long that they didn't have enough time to ask me 2nd algorithmic question. The second interview was much more scheduled and the interviewer was very friendly. Overall algorithmic questions were quite easy but they pay a lot of attention to java skills and architecture design.
