It is usually two to three different interviews. The first one is to know you, your prior experience, and why you would be a good fit for the company. The second one is usually a live coding session where they either ask you to fix a bug or to create a function with specific requirements. They can also give you a take-home project, which is usually to code the John Conway's Game of Life in Ruby or the language you are applying to.

First initial phone screening then one light technical interview with 2 panelists without code only questions and one girl from HR. Overall the style was good and the questions were on point I would qualify the interview as easy if you know the technology, After that I received a take home task, I would strongly suggest the team to give feedback even if you don't get the position as you spend precious time doing the assesment (5-10 hours).
