Overall my process was quick but I went in on an employee referral. One business and one coding test prior to the on-site interview, and two business and two coding tests on-site along with lunch. All of my interviews went exceptionally well and were relatively easy, and I got the coding challenges correct with efficient answers. Gave reasoning for all of my choices and brought up alternatives depending on what the data set may look like and what programming language is being used (software engineering background). Got called the next day to be told the technical part of the interview did not go well and they would not be moving forward. Doesn't seem like a very different experience from a handful of other applicants on here, but what can you do!
