They start with a conversation to know what is your experience, after they send you a project to do involving concurrent programming (you just need to focus on locks and transactions), and then they do an one hour interview with a lot of questions related to databases and queries. This last interview starts easy, just asking for you to make some queries. And then they ask you more deeper questions about strategies to improve performance related to the queries, and after that they ask you a system design question involving converting a file by calling to others systems. In general, the interview is not that difficult but the space is not comfortable. The interviewers don't talk much with you and don't do any reaction when you are answering the questions. Feels like you are following a script that if you don't follow, you lose.
