My process took 3 weeks and looked like this: 1. Screening call. 2. 1 hour technical interview involving coding. 3. 4 hours of technical interviews involving problem solving and coding. The preparation of the interviewers for the final round was mixed, they had issues with their chosen communication/test technologies and offered 2 forms of communication for each interview with no consistency between interviewers. After going through this whole process I was told that I was given no feedback of any kind even when I specifically asked for it.
